Diet Coke and Mentos

Simply drop a Mentos candy into Diet Coke will cause a huge gush of fizz from the top as seen in the picture above.
Diet Coke and Mentos is probably one of the most popular, renown chemical reactions all around. This “Internet Phenomenon” was started in 1999 by a school teacher Lee Marek.
The reaction is caused by the caffeine, potassium benzoate, aspartame, and CO2 gas contained inside of the Diet Coke and the gelatin and gum Arabic ingredients of the Mentos. These together cause an explosive release of CO2 quickly expanding and causing the “Jet” effect.
This can be a safe and fun Chemical reaction experiment. Simply get Diet Coke (As it works the best) and Mentos (Without the Waxy shells).
