It is not normally socially acceptable to play with your food, but in the instance of a ‘coke and mentos eruption’, the entertainment value can throw that perception out of the window. Who introduced the world to this bizzare application of science?
Despite the experiment being shown and explained on a TV chat show in 1999 (by physics student Spencer Tyler), ‘coke and mentos‘ did not take off in popular culture until 2006, when two journalists (David Kestenbaum and Michele Norris) released a blog based on it, and within months video sharing websites such as YouTube were packed with new videos of people trying the creation of a carbonate beverage-based explosion for themselves.
After many tried efforts with a variety of mints (or even fruit-flavoured ‘mentos’) and drinks (such as lemonade) in combination, it is regarded that the combination for a big explosion is to use Diet Coke and Original Mint-flavoured Mentos. This ‘formula’ provides the quickest reaction, and therefore the ‘highest’ explosion, with the Guiness World Record height for an explosion measuring at over 9 meters (with the aid of a nozzle). A testament to the popularity of the ‘coke and mentos’ explosions is that some joke shops now sell mentos with the advertised purpose of causing explosions.
An example of this bizzare experiment can be seen in the video below:
