The Coke & Mentos Rocket Car [Video]

The awesome guys from, whom we interviewed both in 2007 and 2008 (videos), have just released a brand new video showing their new creation at work: a Mentos and Diet Coke powered car. Check it out!

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.
