- Object: Elephant toothpaste refers to a foamy substance that is created as a result of a chemical reaction between hydrogen peroxide, dish soap, and potassium iodide. It is called "elephant toothpaste" because the foamy reaction resembles toothpaste that is being squeezed out of a tube, but on a much larger scale.
- Physical characteristics: Elephant toothpaste is typically a bright and colorful foam that rapidly expands and overflows. The foam is often viscous and sticky in texture. It can have a strong, noticeable scent due to the presence of the hydrogen peroxide and dish soap. The foam is lightweight and can be easily blown away by wind or disturbed by touch.
- Chemical characteristics: The formation of elephant toothpaste involves a chemical reaction between hydrogen peroxide (H2O2), dish soap (containing a surfactant), and a catalyst like potassium iodide (KI). When the hydrogen peroxide decomposes, it produces oxygen gas (O2) and water (H2O). The dish soap helps to create surface tension and stabilize the foam, while the potassium iodide acts as a catalyst to speed up the reaction. The reaction is exothermic, meaning it releases heat energy. The foam is a collection of bubbles containing oxygen gas trapped within the soap and water.
