Why does this happen? This is how Steve Spangler explains it on his website:
Talk about the addition of the yeast as a catalyst, which makes the peroxide molecule release the oxygen atom faster. The teacher who submitted this experiment claims to have done this with hundreds of students from kindergarten through fifth grade and some adults who all loved the experiment. It is very easy and safe to do again at home using regular hydrogen peroxide from the drugstore. - See more at: http://www.stevespanglerscience.com/lab/experiments/elephants-toothpaste#sthash.CY1xT3US.dpuf
