It's a really fun experiment that exhibits this week's science fact, particularly exothermal reactions.
Start with an empty water bottle, add a big squeeze of dish soap, a few lot drops of food coloring (we should have used more color). Then pour 1/2 cup or so of hydrogen peroxide.
In a smaller container mix about 1teaspoon or more yeast to about 2 tablespoons of water. Then pour the water/yeast into the hydrogen peroxide.Observe. Kid is saying, "cool!!!"
Oh yeah baby. Mom is scoring points.
all you need now is an elephant - to brush its teeth.
He was happy until he realized we were out of peroxide. Boo. At this point be sure to feel the bottle. It is warm. Exothermal reactions at work.
