Coke & Mentos Rocket Car

We all know what happens when you combine Coke with Mentos candies (a fizzy explosion).  But have you ever imagined if the force from such an explosion could power a vehicle (of sorts) to move forward in space?  Well wonder no more, people!  Using 108 bottles of Coke Zero and 648 Mentos mints, the “Coke & Mentos guys” have created a rocket car.

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. All that power is pushing against a wall braced with 3,600 pounds of cement blocks. So all the force is directed into moving the Coke Zero & Mentos Rocket Car forward. We get one big push for six feet, and then it’s all coasting from there.

Watch their successful test run in the video above.  Ah, the power of science.
