Super Scientist Zachary did an experiment for Mrs. W’s class called “Elephant Toothpaste.” He used water, yeast, hydrogen peroxide, food coloring, and dishwashing liquid. He mixed these ingredients in an empty bottle, and foam began to rise up and pour over the top of the bottle. It looked like a giant tube of toothpaste! Zachary let every child touch the foam. It felt a little warm because of the exothermic reaction when the yeast and the peroxide work together. This was SO cool, Zachary!
