Image Description: | Detroit, Michigan - A Michigan State University instructor makes liquid toothpaste, sometimes called elephant toothpaste, at Metro Detroit Youth Day. A small amount of the catalyst potassium iodide leads to rapid decomposition of hydrogen peroxide, creating a fountain of foamy bubbles. Thousands of children aged 8-15 attend the annual Youth Day on Belle Isle, which includes games, food, entertainment, and education. |
