What are some Elephant toothpaste fun facts?

Elephant toothpaste is a popular science experiment that demonstrates an exothermic reaction, typically using hydrogen peroxide, soap, and yeast or potassium iodide as catalysts. The reaction produces a large, foamy eruption resembling a giant tube of toothpaste, hence the name. This experiment highlights concepts such as catalysis and the rapid decomposition of hydrogen peroxide. It's safe and visually striking, making it a favorite for educational demonstrations and science fairs.
