Ruben's Flame Tube

Three weeks and one hundred dollars later, we lit our flame tube for the first time. 192 half-inch spaced holes drilled along the length of the 2 inch diameter pipe; a 4 inch speaker sealed to one end connected to a sound source (PC, mp3 player, microphone); a propane inlet at the other end connected to a 20 gallon tank. Once lit, sound waves produced by the speaker can be seen as sine waves in the flames. The higher the frequency, the shorter the wavelength, and vice versa.

Thank-you drmaqueen1289. She's right, we're not retards :-P. As she said, we entered our Ruben's Flame Tube into the Dutchess County Fair Youth Festival. We won first place in our category, beating a Mercedes Benz that had been converted into a bio-fuel engine that ran on vegetable oil (It goes 40mpg!), and a turbine-jet engine go-kart! We plan on entering again next year, but with a different project. If anyone has any ideas of what we should consider building, let us know!

Why does it get flat times to times, when raising/lowering the pitch? e.g. 3:00
