The Coke Zero & Mentos Rocket Car

“After years of work, the Coke & Mentos guys have harnessed the explosive power of these geysers and achieved human propulsion! 108 bottles of Coke Zero and 648 Mentos mints combine to propel EepyBird into the annals of unusual records. The Coke Zero & Mentos Rocket Car uses a piston mechanism: a 6-ft long rod sits inside a 6-ft 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.” LINK, Via: Youtube
