Experimenting with Elephant Toothpaste

Science can be foamy fun! Just ask LVCC at Nazareth Area Intermediate School. While experimenting (under adult supervision) with concentrated hydrogen peroxide, dish detergent and dry yeast, the kids discovered "Elephant Toothpaste." 

Food coloring was added to give the "toothpaste" a cool color. The yeast caused the chemical reaction, acting as a catalyst, to release the extra oxygen gas. And finally, the soap created all the foam.

Fourth and fifth graders, Olivia and Abbi, demonstrate the process.
