Introduction: How to Perform the Genie in a Bottle Demonstration

This Demonstration shows the catalytic decomposition of hydrogen peroxide.

100mL of 30% hydrogen peroxide is pour into a flask that is wrapped in aluminum foil. A small packet of 2 grams of manganesse dioxide MnO2 is wedged between the rubber stopper and the rim of the glass. When opened the packet releases and the reaction starts.

*****Important Note- There must be hole in the rubber stopper (use a 1 hole or two holed rubber stopper) incase the MnO2 reacts prematurely with the H2O2. It is not a sealed container and will not explode.

I believe that the aluminum foil is for heat absorption, so the glass beaker doesn't crack from thermal shock. As cytokine said, the reaction is exothermic, and unless that beaker is Pyrex, it would shatter. This is a guess, and, after all, I'm only 12!

Where can u get hydrogen peroxide 30%

Where can I find manganese dioxide or other catalytic substances for hydrogen peroxide?

Really? Awesome! That I can get a hold of. Thanks.

You could make sooo many movie effects with this. Very cool Is this toxic in any way? I mean can the fumes make you dizzy or something?

regardless of what the answer is, do this in a well ventilated area. As previous posters pointed out, it's steam. steam usually means it's very hot. Not something you want to put your face near

The aluminum foil is to prevent the breakdown of the hydrogen peroxide into "heavy water"; that's why bottles of peroxide are always dark plastic. Light breaks it down.

You can also use beef liver as a catalyst for H2O2. I don't know what catalyst is in beef liver.
