What happens when you combine 200 liters of Diet Coke and over 500 Mentos mints? It’s amazing and completely insane. The first part of this video demonstrates a simple geyser, and the second part shows just how extreme it can get. Over one hundred jets of soda fly into the air in less than three minutes. It’s a hysterical and spectacular mint-powered version of the Bellagio Fountains in Las Vegas, brought to you by the mad scientists at EepyBird.com.

(It really is amazing and completely insane. They’re not just saying it.)
