Hello ! I'd like to make a combination of two great basic physics experiments : 1) The Chladni plate : http://www.youtube.com/watch?v=wio728lLOh0&feature=related 2) Ruben's tube : I'd like to construct a thin parallelepiped (50x1000x1000 mm) with one of the large plate covered with small holes. The speaker would be placed at the center of the other large plate, and the sound would propagate through a big hole at the center of the plate. I'm not asking for help with the construction. I'm rather wondering if this is going to work. So, if this idea doesn't make sense to you, just tell me and give me a little explanation. ;-) Thank you.
