Coke and Mentos Experiment
The Extreme Diet Coke & Mentos Experiments:
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
This is one of the best videos I have seen online in a while, and whoever found that music deserves some credit… it really fits well.
Enjoy,

Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda. In order to form a new bubble, or even to expand a bubble that has already formed, water molecules must push away from each other. It takes extra energy to break this “surface tension.” In other words, water “resists” the expansion of bubbles in the soda.
When you drop the Mentos into the soda, the gelatin and gum arabic from the dissolving candy break the surface tension. This disrupts the water mesh, so that it takes less work to expand and form new bubbles. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites – perfect places for carbon dioxide bubbles to form. As soon as the Mentos hit the soda, bubbles form all over the surface of the candy. Couple this with the fact that the Mentos candies are heavy and sink to the bottom of the bottle and you’ve got a double-whammy. When all this gas is released, it literally pushes all of the liquid up and out of the bottle in an incredible soda blast.
