Ever since our first video that went viral in 2005, people have been dropping Mentos into Diet Coke and other sodas for fun and hopefully for a little science too. No one has been more creative than the guys at Eepy Bird, who recently built a car that runs on Coke and Mentos geysers. This is their second attempt at the car and after some modifications and test drives, they ran it at a local race track.
Their geyser soda car is built using 54 bottles of Coke Zero and 324 Mentos. It runs on a piston mechanism with 6′ tubes attached to the soda bottles. The tubes each have a 6′ rod inside. The pressure from the reaction pushes the rods out of the tubes to push the car off the wall. It’s all coasting from there.
The video of their geyser rocket car has become popular on YouTube. Unfortunately, this isn’t something anyone can build and run themselves. If you want to run your own version of the Mentos Geyser Rocket, check out our Mentos Geyser Car. It’s fun, it’s science and it fits in your arms. Read some reviews on the Geyser car for more information.
