As others said, hydrogen and oxygen gas in the same container will not create water until energy is put in. Fill a Ballon with a balloon with a 2:1 molar ratio of H2 and O2, then pop the Ballon with a flame, and you will get a cloud of water vapor. Without the fire, popping the balloons with a needle will only release the gases.
