The masterminds behind the Mentos/Coke geysers are back, and this time they’re in 3-D!
They’re also harnessing the chemical reaction between Mentos mint candy and Coke Zero soda pop to send a rocket car rolling out of a hangar, to a distance mark of 221 feet.
For “Experiment #321,” Grobe and Voltz built a three-wheeled bike-trailer contraption with 108 two-liter bottles of Coke Zero and 648 Mentos tablets. Their team brought the vehicle to a blimp hangar in Tustin, Calif., pulled a lever to fire up the fountains, and let the CO2 spray push the darn thing across the concrete. Grobe and Voltz celebrated the end of the experiment by clinking champagne glasses filled with Coke Zero. MSNBC
They’ve even done a scientific paper explaining the reason behind the fusion of Coke and Mentos (apparently it’s the sudden mix of bubble-generating surface of mints and the carbonation of the Coke).
And, if you’re impressed with the production values of their latest YouTube video, it may be because it was directed by Rob Cohen of The Fast and the Furious. Hey, it’s even available in 3-D.
Next in their sights? These two guys from Maine are headed to Germany to see if they can achieve another world record of setting off 2,000 Mentos/Coke geysers at once. Tonic.com
