This is a fantastic experiment. I have used it to reinforce a variety of different topics; Endothermic, Exothermic, Enthalpy of combustions, Bond enthalpies, Developing Fuels etc.

Water is separated using electricity. The oxygen and hydrogen travel via a delivery tube to the petri dish that contains a bubble solution. The bubbles are lit with a splint and a loud bang is given off. The only product formed is water.


Hydrogen + Oxygen ---------------> Water
