Coke Zero and Mentos Rocket Car sets world record with 239-feet sprint
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.
