oh yes. but thats a lot of air to get moving so it'll probably not make a good bong

If it was SHORT = smaller = less air....it might work

aerodynamics of bong making?

yes. your lungs hold "x" amount of air. you must be able to pull the air in the tube into your lungs and fill the tube with smoke.

exhale air from tube, then release carb and inhale smoke. if there is too much air in the tube, you can not remove all of this air with your lungs efficiently enough to fill said tube with smoke before said smoke is stale.

I have a good idea... Seal the bottom and make it water proof. Attach a 1 way valve that only lets something into the chamber onto the outside of the tube. Attach a bowl to the end of the valve. Mount a speaker to the top of the tube and play a very low frequency sine wave (like around 2-5hz). After you burn the bowl up, take the speaker out and enjoy your trapped and filtered smoke. An alternative design would keep the speaker mounted and have another one way valve that would lead outside of the tube that you could use as a mouth piece. You can make that valve switchable so that when you're burning the bowl and the sub is moving in and out, nothing is going through the mouth piece. When you want to inhale, just let the sub keep playing and then switch your one way mouthpiece valve on and the sub will force feed the smoke into you.

I made a similar product once using PVC pipes and created a piston like pull valve to extract and expel the air.

wouldnt the sub push as much air as it pulled?

One way valves would only use the energy from one direction and so you would either get suction or blowing... haha.
