The Coke Zero and Mentos Car came into existence way back in 2010. Named EepyBird, the project was developed by Fritz Grobe and Stephen Voltz who apparently have access to a warehouse full of Diet Coke and Mentos since the vehicle they pioneered uses the backyard science gimmick to propel their car.
Each bottle of Coke Zero comes attached with a six-foot long tube that is in turn attached to a six-foot long rod and forms the basic piston mechanism of the Coke Zero and Mentos Rocket Car. When the drink and the Mentos are mixed together, it creates a huge force which pushes the car against a wall braced with 3,600 lbs of cement blocks and the car moves forward. The previous record for the coke-plus-Mentos propelled car was around 217 and the duo tried to improve upon it by creating a Mark II variant of the car, which comes laced with better aerodynamics and boasts of a lighter frame.
The car used the same heady mix of Diet Coke and Mentos though this time around it traveled up to an impressive 239 feet, which apparently is a record. We have no clue how many people out there are trying to create drag cars using Coke and Mentos, but the record is impressive nonetheless. Watch the car in action below.
