The Genie in a Bottle experiment is an exothermic reaction. This means it releases heat.
The soda bottle will get hot and shrink slightly. Oxygen is stored in liquid form in Hydrogen
Peroxide. When we add the Manganese Dioxide (catalyst) it decomposes the Hydrogen
Peroxide and oxygen is formed. The oxygen is rapidly released and steam vapor comes
spewing out the top.
Warning: 30% Hydrogen Peroxide used in this experiment is extremely nasty stuff and will
cause burns if you get even the smallest amount on your skin or eyes. Be very careful and
only do this under adult supervision.

Materials For Genie In A Bottle Exothermic Reaction Experiment
- Clear Plastic Bottle and Cap (1 liter water bottles work well)
- 30% Hydrogen Peroxide (Or Baquacil pool oxidizer 27% Hydrogen Peroxide - sold at pool
supply stores)
- Manganese Dioxide (Ebay)
- Funnel
- Goggles
- Gloves
- Spoon
- Toilet Paper
- String
Process Genie In A Bottle Exothermic Reaction Experiment:
1) Put on gloves and goggles
2) Use the funnel to add enough of the 30% hydrogen peroxide or Baquacil to cover about 1/2
inch of the bottom of the plastic bottle
3) Tear off one square of toilet paper.
4) Use the spoon to put a small scoop of the Manganese Dioxide on in the center of the toilet
paper square.
5) Fold the ends of the square up to form a little pouch.
6) Cut about a 12 inch piece of string. Tie the string around the top of the pouch to prevent
spilling the manganese dioxide.
7) Carefully without tearing the toilet paper slide the pouch into the mouth of the plastic bottle
and lower it 1/2 down. Be careful it does not go all the way down and make contact with the
Hydrogen Peroxide at the bottom.
8) Twist the cap on with the string coming out the bottle. This should secure the pouch
hanging in the middle of the bottle.
9) Set the finished bottle somewhere with easy access to a hose and that can get messy
(just in case).
10) Once ready, remove the cap from the bottle. This will drop the pouch of manganese
dioxide down into the Hydrogen Peroxide.
11) Very quickly step back. Make sure everyone is well away in case it erupts.
12) Make a wish and watch the Genie come out of the bottle.
Hazards
30% hydrogen peroxide is a strong oxidizing agent; contact with eyes and skin should be
avoided. In case of contact, flush with water for at least 15 minutes. Get medical attention if
eyes are affected. Also avoid contact of hydrogen peroxide and combustible materials. 30%
hydrogen peroxide must be stored in its original container.
