Ever seen elephant toothpaste? How about making your own Speedy Freeze. We investigate and exothermic reaction called elephant toothpaste and we make a real Speedy Freeze. Speedway, a gas station in our area sell Speedy Freezes, so I wanted to make something even colder than they are in a cool endothermic reaction!
