Description:
A science experiment that Mary did for her high school chemistry class. The reaction is summarized by this formula:n2 H2O2 ---> 2 H2O=O2nHydrogen peroxide naturally breaks down into water and oxygen. It's stored in an opaque container to help slow down this process. Yeast is used as a catalase to speed up the reaction. Dish soap catches the oxygen and makes bigger bubbles. The foam and bottle feel warn to the touch because the reaction is exothermic- it releases energy as heat. Fun stuff -it was
