foam walkalong glider preview
Bookmarked 718 weeks ago
the foam gliders have come a long way since i made this video for instructions and patterns thin foam or cut your own from scrap packaging foam go here:http:wwwsciencetoymakerorgairsurfkitindexhtm a glider becomes a walkalong glider when you can create a wave of air and surf the glider on the wave indefinitely which looks like magic my middle school technology students have been making and flying paper walkalong gliders but i039ve been searching for a walkalong glider design that039s easier to make and fly for first-time fliers i found it in a wisconsin college engineering student039s work michael thompson figured out how to slice ordinary white styrofoam--either recycled electronics packaging or insulation sheets from building supply stores---into very thin slices then he cuts and forms them into slow-flying gliders including his famous jagwings foam gliders are fast to make slow flying--great for a starter walkalong glidermichael sent me a glider and patiently taught me about them soon my students and i were making them flying them and innovating variations and you can too it039s too early to make instructions yet but here are some notes of what i039ve learned so farmike thompson has agreed to make foam sheets available inexpensively for just a few dollars you can get plenty to experiment with his e-mail is: flyingwingbat at yahoocom replace the quotatquot with i do it that way to foil spambots his prices include postage because he can send them in an envelope and that makes it easy for him to fill orders outside the usabout the videoi039ve been experimenting with a simple hot wire foam cutter this is the crude prototype i039m experimenting with the hot wire is inexpensive nichrome which is short for nickel chromium 40 gauge about 3 thousandths of an inch or 076 mm as thin as human hair when you pass electrical current through nichrome wire there is resistance electrical friction in the form of heat think of toasters i don039t get it hot enough to glow orange for longevity and safety but it039s hot enough to make a smooth precise cut through foami found that two 9 volt batteries hooked in series to get 18 volts was the perfect power source for that length i made a momentary foot switch so i don039t drain the batteries when not actually cuttingto set the thickness at which the wire will cut the foam i started with bare 20 gage wires at the edges that039s too thick so i shimmed it with folder paper oaktag and or printer paper depending how much to shim the wood base is protected from the how wire with aluminum foil the wire will get stuck in the wood and break denser foams electronic packaging can be cut thinner than less dense foam from building center as a rule of thumb i cut as thin as i can without ripping out holes in the foam when i try to separate off the thin sheetmaking a glidertape on a pattern in two places and cut on the line cutting through the tape last separate the foam from the pattern cut out a thin strip of paper from the pattern and tape it onto the frontdecide which side will be up bend the back tips elevons up bend the sliver of paper down what angle will will be one of the things you experiment with if it goes down too fast and you can039t correct it by changing the angle of the paper you might have to cut off some paper if it dips stalls and you can039t fix it by changing the angle of the paper you might have to add tiny bits of tape to the front end of the paperif the glider turns slightly don039t worry about it but if it turns hard bend one elevon up more the elevon opposite the way it039s turning you can also bend the leading edge up on that same side up if the severe turn persists try making the opposite bends on the other sideto fly the walkalong glider once you get it adjusted see this video http:wwwyoutubecomwatchv=7d80mn8rtikit039s about flying paper gliders but it applies to foam as wellmusicmusic is by the great irish guitarist john doyle at a concerti went to the young fiddler was terrific as well duncan wickel

wasp killing machine
Bookmarked 484 weeks ago
wasp killing machine remake of a video from 2008 no-fly zonein the beginning the wasps flew directly to the wire without hesitation now there seems to be a change in the behaviour in the remaining population instead of flying directly into the wire they are now more hesitant many of them seem to be attempting to avoid the wire how can this change in behaviour in the remaining population be explained most likely a wasp can see the wire better than humans can but how is the association with the wire and danger established

what happens when you put 20000 volts into a watermelon
Bookmarked 452 weeks ago
what happens when you pump 20000 joules into a watermelon two words pink mist after trying to blow up a watermelon with a smaller capacitor my friend coyt brought over 4 capacitors rated at 20kv and 25uf each they came from a lab that used to them to simulate the effects of lightning on materials so this is basically like what would happen if a lightning bolt struck a watermelon one cool thing i did not point out in the video is the plasma vortex that happens when we shock the steak the second time it shoots towards my goproi tried some other things like wrapping wire around beer bottles caps to see if the shockwave from an exploding wire would open the caps but the wire kept shorting on itself and it never worked because it never went all the way around the cap i also tried woodburning with the electricity but the bolt just travels on the surface of the wood not inside it even when soaked in saltwaterthanks for my friends coyt and brandon my brother riley and my girlfriend sandra
