Coke and Mentos Fountains

On 15 September, 2007 a group of Dutch people made a new World Record. It was unusual and amazing too. All total of 850 bottles of Coke filled with Mentos goes off at the same time, creating fountains of Mentos Diet Coke! It is a new World Record for creating the largest number of Mentos Diet Coke fountains, at the same moment. This event was held in Breda, Netherlands. Link

A Diet Coke and Mentos eruption (also known as a Mentos eruption, soda geyser or just Diet Coke and Mentos) is a reaction between Mentos candy and cola. The experiment involves dropping several Mentos candies (usually 5–8) into a bottle of diet cola, (note: normal cola can still be used), resulting in an eruption occurring because of rapidly expanding carbon dioxide bubbles on the surface of the Mentos. Producing the reaction has become a popular science experiment and an Internet meme, with videos of Mentos eruptions and even Mentos performance art pieces being posted on sites like Google Video and YouTube.
