Diet Coke & Mentos eruption (a.k.a Coke Geyser) refers to the popular practice of dropping some mint Mentos candies into a two-liter bottle of Diet Coke, which causes the soda to foam at a rapid rate and spew into the air. While other carbonated beverages or similar candies may be used for the experiment, the combination of Diet Coke & Mentos is commonly regarded as the best recipe for maximum output. Due to its spectacular and cost-effective nature, DC&M eruption has become a popular subject topic on internet video sites as well as in the mainstream media. [More on this meme]
