When hydrogen peroxide is combined with soap and a catalyst is added, the hydrogen peroxide decomposes producing heat and releasing oxygen which, due to the soap, generates a large amount of foam (called “elephant toothpaste” by some people). While the generation of a modest amount of elephant toothpaste is often a crowd pleaser at science shows and has even been featured in sitcoms and movies, there are a few rival groups of nerds that are engaged in a cutthroat competition to produce the largest amount of elephant toothpaste ever. The video below chronicles some of the history and the last epic attempt by Nick Uhas and his gang. The end result reminds me a bit of the classic monster movie, The Blob. except that fragments of the stuff even went airborne!
