my dad made this for the grand kids to play with. Hooked up to the air compressor with about 150 psi. To release the bottle just crack a ball valve. Good cheap entertainment.

The only part of this that includes hydrogen is the h in h2o. I was really hoping for more. Stack 5 bottles and hit them with 120 psi of air with a gate valve on a string. Trick is some gravel in the bottom helps keep it straight. Cheers

Yes I suppose your right. I should have used straight hydrogen and gravel. This is just a safe little project that a 4 year old can play with and enjoy. Cheers.

Anybody remember those little red and white water rockets we had as kids? I'm sure I lost 6 or 8 of 'em on rooftops all over the neighborhood....
