video 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.

There isn't anything else in the bottle, just the peroxide solution and the packet of MnO2 after the stopper is removed.
The smoke isn't pink; it's actually steam, the chemistry involved is this:
MnO2 + H2O2 ----> O2 + H2O + Mn+2 (sp)
The reaction is highly exothermic, thusly boiling the water and releasing steam. I think the lighting in the room, or the camera makes it look pink.
I have waaay too much time on my hands :)
2 H2O2 ---MnO2---> 2 H2O + O2
instead of:
MnO2 + H2O2 ----> O2 + H2O + Mn2
Because MnO2 is just a catalyst, it does not react with the H2O2 to make manganese metal.
2H2O2---MnO2--->2H2O+O2
