Urlesque counts down the top 100 viral videos in the history of the web.
diet coke and mentosYou know how people just love to say, "don't try this at home"? Well, some things are meant to be recreated -- with the aid of safety goggles and even a camera for immediate YouTube upload. What I'm talking about are urban legends-turned-DIY experiments (Sprite & Pop Rocks, anyone?) that get on YouTube and go viral. One of the most beloved (and scientifically proven!) displays of science will always be the Diet Coke and Mentos Eruption aka Experiment 137.

The science behind it is simple: mixing the caffeine, potassium benzoate, aspartame, and CO2 in the Diet Coke with the gelatin and gum arabic in the Mentos creates a geyser effect -- causing the foam from the Diet Coke to literally shoot into the air.

So what happens when you combine 200 liters of Diet Coke and over 500 Mentos mints? When Fritz Grobe and Stephen Voltz recreated the Bellagio's famously timed fountains using the two ingredients, the result became a DIY viral masterpiece.

In September 2007, the series of experiments featuring Diet Coke & Mentos not only brought the boys to primetime TV, but won them a Webby, got them nominated for an Emmy and they received over $50,000 for their video -- which was viewed over 10 million times on Revver's video hosting service. Their stunt was even replicated on the Discovery Channel's Mythbusters show.

This DIY experiment still continues to spread across the web -- with hundreds of YouTube copycats garnering inspiration from the original and trying the explosive combination out for themselves.
