Rubens' tube (standing wave flame tube)

I built this tube for a Pre-calc project on harmonic motion.

How it works: http://en.wikipedia.org/wiki/Rubens%27_Tube

Materials:
-1.5m of 2" pvc pipe
-1.5m of 2" aluminum tape
-2" 1/2 watt speaker
-2" pvc endcap
-1 male 3/8" propane fitting
-epoxy
-pvc glue
-electrical tape
-wood used to build a stand

Construction:
-ran the aluminum tape smoothly over the top of the pvc pipe
-drilled 50 1/16" holes through the aluminum tape and the pipe bolow at 2cm spacing
-epoxied and taped the 2" speaker to oe end of the pipe to make a nearly gas-tight cap
-glued the 2" end cap to the other end, and epoxied the propane fitting into it
-built a simple stand to elevate the tube out of 1/4" plywood and a 1m wood post

this was done quick for a group math project, so I had a friend filming, and didn't see the tilt until editing, also, the tube length was set to 51 holes on 2cm centers, to make it exactly 1m, which just fit on the scrap pvc used.

Ideally it would be longer to allow lower frequencies and better sine curves.

you should had just a little bit longer tube and you camera straigt. its tilting abit too much hehe. But nice done!
