“Marek’s Kid Scientists”
A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle. Lee Marek and “Marek’s Kid Scientists” were the first to publicly demonstrate the experiment on the Late Show with David Letterman in 1999. Steve Spangler’s televised demonstration of the eruption in 2005 went viral on YouTube, launching a chain of several other Diet Coke and Mentos experiment viral videos.
