AV Geeks 16mm Lunch 8-8-2023

foreign hi everybody uh I'm skip Alzheimer welcome to the AV Geeks lunchtime streaming show where we watch old 16 millimeter films and think about how it relates to our lives um I spent like 16 hours in Montreal I did a show there uh it was a fundraiser and basically I did it at what was like a outdoor brew pub and I feel like there was 500 people there it was huge giant show uh it was my friend Kayla Janiece put it together and was fundraising for Fantasia Film Festival that was going on and uh I did I showed a film strip that I had people in the audience read and it was in English and some of them read in French which was hilarious and what I learned is that my French is not very good driving around I was like huh what is uh like what is that uh Highway Interstate sign say like I don't know like Is that West or is that East I can't remember um so it was uh yeah it was my dabbling in a country where English was not really spoken it was spoken I mean politely but in a lot of places it wasn't so anyways all right uh so we braved a um crazy storm that came through where it was like two minutes of 60 mile an hour winds that took down a bunch of trees and Power but we were very lucky here at the archive that we did not catch a tree this time uh we have uh had big limbs punch holes and roofs and we've had a tree punch a hole in our roof um it's no fun I mean I love the Big Trees but uh there was a price that is paid uh so we survived it Knocking On knocking on this scanner all right for good luck all right uh here's a film that I don't think we've shown but maybe we have it's called families and rules enjoy foreign [Music] foreign hurry up dinner mothers are always saying that aren't they dinner's ready [Music] four times [Music] come this morning why do you suppose There are rules about coming to dinner on time we're moving well Lisa where were you you came in late tonight every night you're late I'm leaving you're waiting you'll have to read I know you love to read but you have to come to dinner on time too but mommy has to get everything all set and if you're late then Johnny comes late we all come late you know the supper will be way but Laden will beating at nine o'clock instead of it at six so you understand let me see something Johnny you got Clean Hands how about you Reese everybody got Clean Hands maybe your hands don't look dirty so why do families have rules about washing before they eat okay all right that's good oh you can have your juice now but I feel like this is juicer tastes good wanna huh there's to it Marshall Kurt is talking with his mouth full are you talking nobody can understand what he is saying this family likes being together so much you're that they seem to be breaking some rules and when a family breaks rules about eating things can get pretty wild all this playfulness at the table no we hate girls better table manners can you tell which rules Jonna and Risa are forgetting not now not dinner time no I can't hear you Risa and I read can you read not the dinner table no what do you do at a dinner table yeah that's right that's right well why don't you do that then you do know that the table man has done then I have to have another one you'll have to have another what dear thank you there's your napkin right there I know but I've got enough why because you know me I don't know you now why do you want another napkin yes I meant waste twins pajama at 7 30 it's time for bed no this is rules tell us what to do and what not to do and there must be some sort of penalty if they are not followed you know why you're going to bed you're being punished no you're very unhappy look at mother darling bothering him and I've told you repeatedly you are not to do that you're going to bed at 7 30 tonight [Music] Erica is older than you are she didn't even go to bed that early when you're that old then you're always going to bed that late too rules aren't always easy to follow and nobody likes to be punished Janna is angry and she goes into Kurt's room and thinks that maybe she'll break one of his toys [Music] um well I guess when we're angry we think about doing silly things [Music] children breakfast time comes [Music] mommy where's my library book children breakfast is ready it's about time well after all my library book I can't find my sneaker and I can't find my place oh children you did you look properly everywhere does your family have a rule about getting up on time for breakfast and on time to get to school the Leland family needs a plan to make this rule work Howard breakfast is ready I was here breakfast is ready to say I'm listening juice even dad needs a better plan for getting up early enough in the morning oh what a morning sometimes we have to change a rule that isn't needed anymore I don't know [Music] what's going on here what is going on mommy Lisa won't hold my hand Mommy I don't want to hold her hand I'm too old too well Reese I think that's a very good point perhaps you are too old now grown up a little you may walk just side by side dear all right girls I think you better move along now and have a good day [Music] tonight the Leland family is following a new family rule for planning ahead everyone wants to be ready to leave early the next morning on their trip sure because they have planned watch how well everything works Jana has packed the clothes she wants to take Kurt has his toys Erica has her books and mother is in charge of the food [Music] father's responsibility is to work out which roads they will use [Music] everybody has planned and then carried out his own responsibilities [Music] as well can this be the same family we all know [Music] they seem to have followed their rules and their rules work because they planned ahead now they can get away bright and early for their trip they haven't forgotten the thing [Music] have our lunch here [Music] [Music] foreign [Music] thank you [Music] oh Mom and Dad you forgot to cancel the milk and hold the mail uh yeah so I think I'm gonna look this up real quick Visions uh Association what is it Vision Visions Associates Incorporated uh I feel like they were African-American owned um educational film company very generic so I'm going to take some time and figure this out uh Vision Associates short documentary film anyways you don't need to have me watch and look at Google uh let's watch the next film uh this is on the film scanner this is called climb enjoy where we spend the first night sure looks like a long way from there to the top yeah I know but I'm sure that's it I wonder how hard it's going to be yes we'll know soon enough [Music] all right [Music] we talked about the climb for a long time and then one weekend I met Mike in the valley and we sat around sorting out all the gear we need for a multi-day Ascent of this sort [Music] now it had snowed two days before and although it had melted off we decided to take along plenty of winter down gear just in case we got caught in another storm up there and then after about four or five hours we we had it all together and we're ready to go [Music] we walked across the meadows and at the talus slope I remember when we got to the base of the climb we didn't say much I think one of the hardest things about a long wall like this is just sort of convincing yourself to get off the ground it's a commitment and physically and mentally you have to be prepared for it but obviously you don't make a commitment like this until you're ready so there at the base we were concerned about the dangers we'd be facing but really just excited about the joy of climbing and reaching the summit [Music] I take the first lead that morning I put the pitons and carabiners around my shoulder on slings and and started off up the wall [Music] you climb up a ways you put a pin in the crack for protection and you step out on that wall it's just like like stepping into another world sometimes it's it's very strenuous other times it's just very poetic and very free it's kind of like a chess game and you have to think two or three moves in advance and the better climber you are the more moves and Advance you're capable of adjusting to [Music] foreign [Music] [Music] Russ had reached the end of the first pitch or rope length and I was to be climbing second moving up a rope on jumars jumars are ascenders that slide in One Direction and lock in the other I'll be going up a fixed rope that's tied off because on a big wall like this Russ has other things to do you'll be bringing up the hall bag with all our food and water and extra gear I was cleaning the pitch removing all the pitons that Russ used for protection so we could use them again a rhythm begins and the ground starts to disappear below foreign by late afternoon we'd reached a place called dinner ledge a small outcrop of rock about 800 feet up you know one of the first things you want to do is get the hall bag open and get out some water you get extremely thirsty up there and yet water turns out to be the heaviest single thing you carry so you have to ration yourself to just six cups a day for men for dinner we had gorp gorp is a mixture of candies and nuts and raisins outstanding you know it's a meal that usually is inhaled rather than eaten [Music] the first time you spend a night on a wall you know it's frightening but we'd both been up there on walls before and and finally you get used to that environment even looking up at where we'd have to go the next day in fact you know we ended up talking about we ended up talking about another climb I was excited about some climate I'd done across the valley and was pointing it out to Mike and we just sat there debating the various pros and cons of the root mm-hmm finally it gets dark and you tie yourself into the mountain so you don't roll off in the middle of the night you get in your sleeping bag and watch the stars come out [Music] it's really hard to get up in the morning especially if you haven't slept much the night before you lie there on the ledge thinking oh God I'm still here [Music] I took the first lead again and began to work my way slowly up to a large overhang that was above us the overhang turned out to be the mental Crux of the climb I think there's there's really harder physical climbing up higher but but sometimes it's just very difficult to get yourself to go out on an overhang and yet if we were going to continue I'd have to work my way about 15 feet straight out from the wall [Music] thank you [Music] and the hardest part of the overhang turns out to be the last part because you get all the way out there and then you've got to reach over the lip now there's a crack up there but you you can't see it and you don't know whether you're going to be able to get a pin in or if you do whether you'll have the strength to hit it hard enough so it'll hold when you stand on it it's extremely strenuous and yet and yet you find you just have no conception of time that concentration has completely erased it and all that's left is a tremendous desire to get over that bulge [Music] and yet it's at times like these when when physically and mentally you're pressed right to your limits if that's really when you find out what climbing is all about because you're finding out what you're all about and what your limits are and how you react when you're pressed right to them and then finally you've got to commit to it you know you've got to stand on that PIN so do it do it now [Music] I stood up and and the piton held [Music] and then you've got this incredible desire to get another pin in the mountain [Music] and then you can relax at least relax in the comparative safety of a single piton just about the time you're beginning to congratulate yourself on what a fantastic job you've done on the overhang you can always look up the wall and see where you still have to go Russ had reached the end of another pitch this time there was no ledge to stand on so he tied himself off the pins in the mountains I'd be moving up on those jumars although it's it's physically a little easier it has its own mental problems you're working your way out along and you try not to think of where you're going to be when you take that last pin out from the overhang but any if anything goes wrong out there the odds are that you've got no one to blame but yourself that really becomes one of the nice things about climbing you find that there are no scapegoats on a big wall that means that you're responsible for your own defeats but you get the joys of your own victories a good deal of time you're out there just by yourself [Music] the day wears on the climb continues and although most of the time you are by yourself out there there's a wonderful bond that grows up between you and and your climbing partner you're going through highly emotional experiences leading your you're sharing them together on ledges your planning strategy you're always tied together by that long length of rope for safety and and that rope just seems to get stronger the higher you go especially when you get into a little trouble I got up to another overhang and I put in a pin above it and yet as I stepped out I was totally enmeshed in all of my lines and and you want to go up but but you can't go up and and you want to go down and you can't do that either you find you're you're not only putting out a tremendous amount of physical energy but a lot of emotional energy as well you begin to lose control of your mind you look around and you see where you are and it just all comes rushing in on you you're not only fighting with a mountain but you're fighting with your own head because if you lose control of that up there you're in real trouble [Music] people talk about climbing and they say it's kind of a death wish but when you're really out there in a situation like that every one of those moves is more an affirmation of life [Music] when you climb you follow the crack systems but sometimes those cracks just disappear and that's what happened at the end of the next pitch Mike began yelling down that there was no more crack to climb in I began yelling up that it would really be nice if he went and looked for one so he began to set up a pendulum he's climbed up the crack as far as he can go and put pins in now I'll let him back down the face about 40 feet when he gets down there he'll become the weight on a pendulum a human way to swing back and forth across the wall and and look for a new crack system by which we can continue [Music] thank you you've got to make it and yet your mind starts to say I can't do it I can't throw myself at it or I'll fall and then you do fall and for a moment there you think it's all over but you find you're still up there you're still hanging on that rope eventually there's nothing left to do but just get it together and try again [Music] [Music] thank you [Music] [Music] [Laughter] okay you climbed higher and that bond gets stronger sharing of weaknesses and strengths of seeing each other for what you are and now that second day is drawing to a close although we're 1800 feet off the ground we're still several pitches from The Summit and if we're going to make it by Nightfall I'd have to climb a difficult Jam crack my jam crack is where there really aren't any holes in the Rock to grab onto so what you do is you place your whole arm in the crack where it's thin you make a fist so your fist is thicker than the crack and then you pull yourself up on it you put your other arm in you wedge your feet in the same way move slowly up the crack you have to hold yourself to the mountain with one arm while the other wrestles with with carabiners and ropes and pitons [Music] Jam cracks can obviously be very strenuous I got to this point I got some protection in and yet as I turn to continue I just couldn't seem to find a hole that I wanted to commit to and when you're leading you don't want to move until you're ready so I worked here for for about 15 minutes with with one arm and then the other finally putting in some more protection to catch me if I came off and yet finally no matter how sweaty your arm is you just have to tell yourself trust it trust it time and again as a climber you're forced to trust to put your faith in your own ability to just drive yourself out beyond your limits until finally a very beautiful state of self-reliance is reached where where the particular climbing problem the summit the mountain all of them are unimportant and your mind is free to go beyond these things after you've gotten to a Ledge especially like this where you really had to struggle to get there you've got the whole bag up and you can relax it's one of the most beautiful times in climbing you put out a tremendous amount of energy and concentration and now adrenaline is beginning to break down on your system and your mind and your body relax and in a way they just never have before and you find you're very much in the present very much into them you look around and everything has a wonderful kind of importance to it [Music] [Music] [Music] and Mike was up to the ledge and climbing past me he was really climbing quickly you know inevitably you reach a point where you're just exhausted what you want to do is try and make it at the top and hopefully before it gets dark we started up a chimney and the angle of the mountain finally began to break we could we could see a tree way up above we knew that was on the summit just climbing like mad now trying to make it [Music] foreign [Music] 's reached a challenge met and did you sit up there and you ask yourself why do you climb and and it's still not easy to put it into words sure you'll be you'll be strung out on a pitch or flat up against the wall on a legend and you'll find yourself saying you know why am I here I got to be out of my mind and yet for reasons underneath that you just wouldn't want to be anywhere else [Music] 74 is when that film was made um and it's during a time where there's a lot of these introspective films uh outdoor kind of extreme sports but not really extreme um they're so low there's up you know these are of course titles that were used later in the 2000s but it's all related to climbing or hang gliding or whatever it's kind of on the and the path from uh Endless Summer the surfing feature film um all right uh let's learn about some insects and their control I'm sorry insect enemies and their control enjoy [Music] this is an entomologist a person who specializes in the study of insects many of the thousands of kinds of insects these scientists study are helpful to mankind fruit flies for example are useful in studies of heredity bees and other insects are helpful in pollinating flowers some insects act as scavengers eating bits of dead animal and plant matter however there is a small but very important segment of the total insect population that destroys our crops endangers our health the health of our domestic animals and damages our homes by understanding the habits of insects their life cycles their structures and their physiology entomologists are able to carry on a more effective battle against the enormous damage that harmful insects cause us entomologists are often called upon to identify insect specimens found in plants quarantine inspectors some of whom are entomologists prevent infested plants from coming into the country corn for example is a crop that is attacked by an insect pest accidentally brought into the United States the European corn borer The cornborough Moth lays eggs on the undersides of corn leaves in June these hatch into destructive larvae which in turn are followed by a second generation of malls and larvae in early August the second brood larvae eat and destroy the stalks and ears to combat this pest some Farmers delay their date of planting this results in the corn being small and having little food value for the first generation larvae when they are ready to hatch planting insect resistant varieties of corn also reduces crop damage one of the common measures of control against the European corn borer is the application of chemical insecticides control measures against insect pests are absolutely necessary for the production of our fruit crops one insect which does damage to the Apple crop is the coddling moth the coddling walls lay their eggs on the leaves and twigs of apple trees in the spring the larvae feed briefly on the leaves and then eat their way into the apples after feeding on the seeds within the cores the larvae leave the apples and find a sheltered place to spin their cocoons these cocoons are on a discarded wooden box the larvae in the cocoons can be destroyed by burning such containers and other debris that accumulate in apple orchards frequent spraying of apple trees with insecticides during the growing season also helps prevent damage from The coddling Moth each year cotton crops are damaged by the larvae of The Boll Weevil the adult weevil's long snout is used to bore an opening in the bowl which contains the developing cotton the insect lays eggs in the hole it makes and the larvae which hatch begin to eat inside the bowl the result of this destruction is no cotton or at best short discolored fiber which has little commercial value dusting cotton fields from the air with insecticides is an effective method of protection from the bowl weevil there are many kinds of insecticides needed to control insects some will kill chewing insects such as grasshoppers While others will destroy sucking insects such as aphids aphids and other insects are also eaten by birds birds are an important natural control of insects and so conserving our bird life is another way of controlling harmful insects some insects are killed by other insects this parasitic wasp is depositing her eggs in a caterpillar the larvae get their nourishment from the body of the insect host then the larvae spin cocoons which we see on the skin of this caterpillar eventually the infested insect dies orange trees and other citrus fruits are sometimes injured by the cottony cushion scale a small sucking insect which feeds on the trees and fruit lady beetles are a natural enemy of the cottony cushion scale and they are sometimes placed in groves the lady beetles destroy the scale but insects do damage other than to our crops some insects such as the common housefly are dangerous to our health flies carry disease germs on the hairy portions of their legs house flies feed on decaying matter in which they also lay their eggs the eggs in turn hatch into larvae called maggots by wrapping garbage and by sealing containers we can prevent adult flies from reaching wastes where they may lay their eggs screens will protect our homes against flies mosquitoes and other insect pests too mosquitoes are blood sucking insects the qlex and aedes mosquitoes are mainly a nuisance biting their victims and causing minor irritation but some mosquitoes are serious threats to health the anopheles mosquito for example carries the microorganism causing malaria mosquito larvae live in water and breathe through tubes which penetrate the surface of the water to destroy these larvae safe insecticides are used which form a film on the water the chemical film kills the larvae by contact with them considerable damage is done in our households every year by another insect the common clothes moth damage is not done by the adult moth but by the larvae which feed on Woolen fabric garments can be protected against closed moths by dry cleaning and by using paradichlorobenzene crystals the vapors from these crystals keep away the adult moths that lay the eggs termites are insect pests which also infest homes in a different way they may be found in the ground or in wooden structures of buildings the food of termites is wood or cellulose in some form and within their intestines are microscopic protozoa which digest the cellulose treating the soil around foundations of buildings with a long lasting chemical is the preferred method of preventing termite damage the chemical forms a toxic barrier which termites cannot penetrate this was once a beautiful elm tree we can see what caused its destruction by peeling off the dead bark here we see the pattern of marks made by the burrowing of the European elm bark beetles which carry the Dutch elm disease fungus infected trees are removed and burned in order to destroy breeding places of these insects and prevent dutch-one disease from spreading to healthy trees the war against all insect pests is a never-ending struggle methods are being continually applied to combat insects that destroy food crops insects that affect our health and insects that cause damage to our property all of us benefit from the many different control methods which are used in the continuing fight against harmful insects [Music] thank you Coronet for that uh so to update a Visions Associates was not an African-American educational film company there's another one I'm still trying to hunt it down to figure out what it what it was um maybe I'll find out uh show or it might be something I will highlight in the future in the future uh yeah let's conserve some uh Water Resources today [Music] a century ago a few gallons of water a day provided a person's daily needs in the United States by 1900 40 billion gallons of water were being used daily in the United States an average of more than 500 gallons per person daily today our water consumption has increased to more than 350 billion gallons a day an average of more than 2 000 gallons per person daily water for domestic use for irrigation and for industrial use water water and more water is needed as communities get larger and industries expand industrial needs are measured today in thousands of billions of gallons yearly for example it takes 40 000 gallons of water to manufacture one ton of paper it takes 110 000 gallons to produce one ton of Steel steel for many uses but the greatest single use for fresh water in the United States is for irrigating farmlands 75 to 100 billion gallons of water a day one half of the cotton in the western states is grown on irrigated land one acre of cotton during the growing season will require about six hundred thousand gallons of water all the water we use falls to the Earth as precipitation rain or snow water that isn't soaked up by the ground or evaporated Finds Its way into Brooks or streams and then to rivers or lakes the fresh water in rivers and lakes is what we call surface water much of this surface water eventually flows into the salt water of the oceans where it is costly to reclaim we can increase our supply of surface water a major source of all water by keeping water on the land a dam keeps tremendous quantities of surface water on the land by creating a reservoir which raises the level of the river Upstream whenever more water is needed to supply communities Dam gates are opened and water is allowed to flow Downstream some water is diverted into concrete aqueducts such as this which transport water to where it is needed for irrigation in an irrigated field the surface water from the river finally goes back onto the land vegetation such as grasses and other plants also holds water on land slowing the runoff of rain and checking erosion on the other hand a field which lacks a good plant cover can become eroded rain water running off the slopes of this Farm has washed away tons of fertile topsoil and carved gullies eroded soil from such a field is washed into rivers as silt check dams are built across gullies and Ravines to slow down the runoff of water to prevent erosion Terraces low Ridges of Earth check the runoff of water on farmland contour plowing also conserves Water by helping to prevent erosion strip cropping is another Farm practice designed to hold water on land alternate strips of a cover crop such as grass and a field crop are planted the strips of vegetation check the force of water running off the cultivated soil surface water that filters down through the topsoil through the subsoil and into the tiny pore spaces of the Bedrock is called groundwater groundwater is another major source of water the ocean is the primary source of all water on the land when water evaporates from the ocean's surface it moves into the atmosphere and forms clouds later it falls again as rain or some other form of precipitation precipitation from clouds may fall on both water and land some of the groundwater is used by growing plants and some of it percolates down into deeper zones this groundwater May emerge in another place as a spring to become surface water the water in this spring as well as all runoff water will eventually return to the ocean or other bodies of surface water some surface water as well as groundwater evaporates back into the atmosphere and may condense into clouds this process of evaporation precipitation and storage is the water cycle a never-ending circulation of water from the ocean and the land into the atmosphere and back to the land and ocean while some groundwater May emerge from the earth in the form of Springs we get much of our water from Wells sunk into the Earth to tap the groundwater underground reserves of water contain the largest storage of fresh water in the United States for many years over most of the United States groundwater has been used up much faster than it has been replenished building a water spreading system is one way to replenish deposits of groundwater here a sand pit has been filled with water the water gradually seeps through the sand and deep into the ground so we have seen some ways to conserve our ground and surface water reusing water will also help us conserve our water supplies one way to reuse surface and groundwater is by purification in this purification plant domestic sewage is treated to remove organic and mineral wastes water containing industrial wastes should be treated in the industrial plant so that it is free of waste before being returned to its source generally contaminated water should be disposed by means of an effective sewage system many cities use a combination of methods in keeping waste out of the water supply for example Chicago once dumped its sewage into Lake Michigan as the city grew another method of sewage disposal had to be found the Chicago sanitary Canal was dug to carry waste away from the lake and down to the Mississippi River in some cities organic wastes are processed into fertilizer which is then bagged and sold as a commercial product some cities empty their sewage into large bodies of water such as the sea or large lakes thus creating a possible source of contamination for beaches cities also have a problem in securing fresh water some of the water for the Los Angeles area is supplied by the Colorado River huge aqueducts carry the water a distance of 250 miles in the near future the water shortage problem may be solved by a new source of fresh water this plant converts seawater into fresh water scientists are finding ways to reduce the cost of salt water conversion converting salt water will give us an increasing supply of fresh water for our growing needs already we require over 200 billion gallons of water daily for industry washing drinking Sanitation Recreation and irrigation but we have seen that we can conserve the water resources available to us in three important ways by keeping surface water on the land by carefully replenishing our supply of groundwater and by reusing water after it's been purified conserving our water supply is part of our conservation of all natural resources water conservation is a key to an abundant future for our country of all our conservation problems none is more important than conserving our water for now and for the future [Music] next to use ears in the future [Music] um that problem has not changed and it's gotten worse so we knew about it at least 60 years ago if not before then anyways thanks for tuning in today very much appreciate your eyeballs uh yeah one way you can support us is by hitting the Thumbs Up Button by commenting if you're in the Raleigh Durham triangle area I'm doing a show tonight at the Alamo Drafthouse at seven o'clock it's a free show in the video Vortex lounge and we're gonna watch films about
