What happens when you mix 54 bottles of Coke Zero and 324 Mentos mints together? Well apparently you have a Coke and Mentos Rocket Car. This one is the Mark II; they claim it is smaller, lighter, sleeker, and faster than the Mark 1 (I missed the Mark 1 somehow 🙂 )
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.
Don’t Try This at Home!
