'Rocket car' blasts off on Coke and Mentos

Have you ever dropped a Mentos into a Coke? It fizzes up real bad, like one of those baking-soda volcanoes we all made as kids. Comedy/science duo EepyBird decided to see how far they could take the concept, hooking up a "rocket car" with 108 two-liter bottles of Coke and 648 Mentos.

From EepyBird:

The Coke Zero & Mentos Rocket Car uses a piston mechanism: a six-foot-long rod sits inside a six-foot-long tube attached to each bottle of Coke Zero. When the Mentos drop into the soda, the pressure tries to push the rod out of the tube. With 108 rods all pushing at once, that gives us a lot of power.

They managed to go over 200 feet off the power of that push, too. And hey, think about it — if we lose all of our oil thanks to BP, at least we have an alternative to the gas-powered car right here.
