And where did all that water come from anyway? It can't be easy to combine hydrogen and oxygen like that.
Also consider: Hydrogen is extremely flammable, and Oxygen supports combustion. If you fired a squib in a roomful of Hydrogen and Oxygen, you'd get a huge fire. If you spray Hydrogen and Oxygen on it in the form of water, it puts it out. You can breath them in the form of air, but not in the form of water.
