Water into Rocket Fuel?
Turning the handle makes electricity which flows to electrodes in the water. The electrical energy splits the water into its two elements, hydrogen and oxygen. Hydrogen burns quickly and is used as fuel for the rocket. Hydrogen bubbles can be seen coming from the negative (-) electrode, oxygen bubbles from the positive (+) electrode. The gases are collected until there is enough to launch the rocket. Pressing the button starts the launch sequence; the hydrogen fuel and oxygen are fed to the combustion chamber, making an explosive mixture. A spark then ignites it, the two elements combining to form water. A lot of heat is made so the water is in the form of steam. This expanding gas forces the rocket up into the air.
