Hydrogen Peroxide, Liver, and Elephant Toothpaste Science?

Craig Beals from Beals Science looks at the biochemistry of beef liver and hydrogen peroxide. Liver is full of catalase, an enzyme catalyst that decomposes hydrogen peroxide into water and oxygen gas. Craig experiments with 3% and 30% hydrogen peroxide on liver to compare reaction rates. Then he makes Elephant Toothpaste using a hydrogen peroxide, dish soap and potassium iodide (KI). The potassium iodide acts as a catalyst for hydrogen peroxide just like the catalase did in the liver. The result is a classic chemistry demonstration called "Old Foamy" or "Elephant Toothpaste".
