What % of hydrogen? im thinking of putting a hho generator in the coke can agap of course, or will it be to slow?

I put one in a jam jar.
Doesn't put out very much hydrogen, but it's pretty potent. I add some butane for extra power.

I will measure the cc's per sec for you at 12 v, .5 amps.

I have an old cannon, my very first, that I really dident spend any money on, its just old pvc parts that I dident use for another pvc project. I might stick it up. If not, I will try another idea.

@Crna Legija

I measured the production rate. It's about 1 cc/sec.

Ok, finished mine. Very simple, and made with old stuff I had laying around. I will get pictures up soon, but here is the description. Parts, Water bottle, schrader valve. That's it. Just simply fill up with air, hold onto the end cap, and twist the bottle till it launches. Simple and ghetto huh? I will get pictuers up tonight or something.

Haha, I will try to get a video, I decided to go with a gatorade bottle (much more surface area on the cap for the schrader...), plus it can hold a lil bit more air, and the walls are thicker.

That I would have to debate. Make sure to wear your safety glasses. :wink:

Yeah I just figured that out. I just installed the schrader into the cap, and inflated the bottle... At only 40psi it inflated and puffed out quite a bit. I may just use a regular water bottle.

More amps is better.

I measured the rate by holding a syringe under water, and filled it during two seconds. (counted with a stopwatch), and after that I divided by two.

It was made when I was bored, and wanted something to make bangs without sulfur smell.
I wouldn't make it just for firing a mini :D
