Paul Kelter: OK ready? Lechaim!

Kelter pours the crystals of hydrogen peroxide into the test tube that contains the food coloring. The reaction causes a brown and white foam to rise and exude from the test tube.

Paul Kelter: Let's get a side shot. There you go.

The camera view changes from a view of Kelter and the test tube to a closeup of the test tube as viewed from the left. The foam continues to flow out of the tube.

(singing) Oh, wouldn't it be lovely? All I want is….

The camera view changes back to the view of Kelter and the test tube.

Notice the exothermic nature of the reaction. Can you see the steam coming off the top?
I wouldn't be surprised at all if the hydrogen peroxide is just forcing the breaking apart of the food coloring because it's so strong an oxidizing agent. It's so very, very reactive. Isn't that beautiful?

Now this is very interesting because you can talk about exothermic reactions, obviously spontaneous, effect of a catalyst, stoichiometry, and, you can talk about formation of oxygen.

Please, do not touch the fuzz.
