Science can be fun. :)
The overall equation for this reaction is:
2 H2O2 → 2 H2O + O2
However, the decomposition of the hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2) is catalyzed by the iodide ion I from KI (potassium iodide).
H2O2 + I- → OI- + H2O
H2O2 + OI- → I- + H2O + O2
The dishwashing liquid captures the oxygen as bubbles.
It is recommended to wear safety glasses, they are just a few cents each, when doing experiments for fun. :)
I hope more people will consider majoring in science, math or engineering
. The world would be a better place if more people knew more science, since we would find solutions much faster to the challenges we face. :) Science & technology allow for a lot of artistic expression, so one can do art while being a geek or nerd. :)
Science will allow us to bring what is thought of as sci-fi or magic into the everyday reality, things like curing aging or eternal youth, telepathy, teleportation, shapeshifting, physical immortality, world peace

(some videos feature the Google Director of Engineering who talks of Physical Immortality often
