Hydrogen gas and Oxygen gas to water

[txrandom]

How would I convert H2 gas and O2 gas to water without making explosion? How would you slowly react the two ingredients and capture the water vapor at the same time?

It's fire. Burn hydrogen in the presence of oxygen and you get water. Carefully control the inflow of gasses and you're good. it's essentially a tiny low powered engine.

I'm trying to figure out if it would be viable to purify water through electrolysis and then burning it back to form water. Preferably with some batteries, empty pots, and flame.

What you are wanting to do is effectively what fuel-cells do.

That seems terribly inefficient and unnecessary, unless you want to use the energy from burning the hydrogen as well... what's wrong with distillation?

We're learning about electrolysis and voltaic cells, and I got to thinking about purifying water. Distilling water would probably be a whole lot easier and safer.

But if I want to mess around with explosions, H2 and O2 gas would be cooler. I wonder if modifying my potato gun to use H2 and O2 gas would be funner. I just got to make sure I don't put too much in and send flying pieces of PVC into myself.
