Hydrogen peroxide is made up of water and oxygen - H2O2. In this experiment, the molecule is torn apart by a catalyst... manganese dioxide. (The hydrogen peroxide used in this video is 30% and not available in your local store). The secret to releasing the genie when the bottle is opened is placing the manganese dioxide on a string and hanging it above the hydrogen peroxide. When the cork is pulled, the string drops down into the liquid, starting the reaction... and releasing the genie from the bottle. The Genie in a Bottle is an example of an exothermic reaction because it releases heat. Touch the "genie bottle" and you will feel it become hot.
