An Even Bigger Mentos Fountain

The guys at Eepybird have done it again. They just released a new video with more Mentos and Diet Coke explosions and this time it has a twist. They must have a lot of time on their hands, because this time they use a domino effect and twice as many bottles than in the original.

    Thanks emty. As you probably know, soda pop is basically sugar (or diet sweetener), flavoring, water and preservatives. The thing that makes soda bubbly is invisible carbon dioxide gas, which is pumped into bottles at the bottling factory using tons of pressure. If you shake the bottle and then open it, the gas is released from the protective hold of the water molecules and escapes with a whoosh, taking some of the soda along with it. Many scientists, including Lee Marek, claim that the Mentos phenomenon is a physical reaction, not a chemical one. Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda.
