Introduction: Air Bazooka

In this video I'll show you how you can make a DIY air bazooka (vortex cannon) using a bunch of junk laying around the house!  Everything I used in this video I just had laying around so it cost me nothing to make.

Question: Do you think this would shoot a bubble ring of air underwater if aimed from above water?

Interesting. What if you put a (short) tube to drive the air jet?

I'm afraid I'm not quite sure what you mean. Do you think you can explain this in a little more detail? Maybe I'll give it a try.

I think you could try what happens putting a barrel (cannon | tube) in the exhaust hole. Pardon my "yes bwana" English.

Oh I understand now. That's a good idea! I've read about people actually using a cone shape for the barrel of an air cannon. I'm not sure of the science behind it but it sounds like a conical barrel can help the vortex somehow.

Please PM me when you have done it. Not only conical, also a cylindrical tube would change the effect, enhancing or worse.

I'll be sure to let you know if I give it a try.

My lid is very hard and I can't cut it. Suggestion?

rimar2000 (author)insaneboss112013-06-20

If it is plastic, try a hot stiff wire. Heat it over the gas flame.

Hmmm... Maybe you can try holding the plastic/latex on with a rubber band? Then you can just disregard the cover altogether. Try stretching the diaphragm material over the edge of the lid and then stretching a rubber band around it to hold it in place. I would think that would work, although it won't be quite as secure.
