About The Coke Zero & Mentos Rocket Car: Mark II
After years of work, we've harnessed the explosive power of Coke and Mentos and achieved human propulsion! 54 bottles of Coke Zero and 324 Mentos mints combine to propel EepyBird into the annals of bizarre records. After the success of the Mark I, this is the Mark II: smaller, lighter, sleeker, faster... And farther! Yep, this vehicle went farther than the Mark I, with just half the fuel.

The music track is System Countdown by our friends at AudioBody off their album Do Something Difficult.

How Does This Work?
This is one not to try at home.

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 54 rods all pushing at once, that gives us a lot of power.

All that power is pushing against a solid wall that's attached to a sheet of plywood that runs under the rocket car itself -- so the wall won't move, the rocket car will. We get one big push for six feet, and then it’s all coasting from there.

Don’t Try This at Home!
Seriously, don’t try this at home. There is a huge amount of power involved, and we don’t want you to get hurt.

What you can (and should) try at home is the Coke & Mentos geyser: you can get your own Coke and Mentos Kit: EepyBird's Diet Coke and Mentos Kit which includes nozzles just like the ones we use in our geyser videos, or you can click here: Make Your Own Coke & Mentos Geysers to learn how you can make Coke and Mentos geysers with stuff from around your house.
