A Diet Coke and Mentos Eruption (also known as a Mentos eruption, soda geyser or just Diet Coke and Mentos) is a reaction when certain objects are dropped into carbonated liquids. The most well-known example of this reaction (among many possibilities) is the specific combination of Mentos candy and Diet Coke, typically achieved by dropping several candies into a bottle of the cola. This results in a jet of cola from the mouth of the bottle due to the rapid expanding of carbon dioxide bubbles on the surface of the candy. Producing the reaction has become a popular science experiment and an Internet meme, with videos of eruptions and even performance art pieces being posted on websites like Google Video and YouTube.
