Ruben’s Tube: Higher the frequency higher the waves
Classic experiment in physics involving propane, a pvc tube, a speaker…and a crazy dude. Ok he’s maybe he’s not entirely crazy, and this is a pretty damn fun way to waste an afternoon probably. Basically you have to poke a bunch of holes in the tube and run the gas into it. Then you manipulate the flame with sound…just watch the video it’s one of those cases where my lame attempt to explain it falls short…A search on Youtube brings up a few (million) more examples.
