The Mentos and Diet Coke guys are back -- in 3D! Almost four years to the day after Stephen Voltz and Fritz Grobe posted the (literally) explosive video featuring the Vegas-worthy fountains that they created from nothing more than Mentos dropped into two-liter bottles of Diet Coke, the pair has returned with a striking new gambit.
Their latest feat? A rocket car powered by (you guessed it) Mentos and Coke Zero. If, in an age of evermore rapid technological advancement, four years seems like a long time to wait for the next generation of candy-and-soda fueled propulsion, it's not like Voltz and Grobe have been holed up in their lab in Buckfield, Maine the whole time. What started out as a backyard gag of the "dude, do you know what happens when you mix Mentos and Coke" variety turned into one of the most viral videos of all time and quickly launched the duo into the stratosphere of internet-born celebrity, with appearances everywhere from Letterman to Ellen, corporate-speaking gigs, performances with the Blue Man Group, and videos for Barenaked Ladies and Weezer.
The video after the jump.
But for the moment, at least, Voltz and Grobe have returned to their quasi-scientific roots. (Voltz is a former trial lawyer from Boston; Grobe abandoned studying mathematics at Yale to become a professional juggler.) With it's unwieldy battery of PVC pipe, 108 bottles of Coke Zero and 648 Mentos, their rocket car may appear to be a disappointingly Rube Goldberg contraption to anyone who had hopes that the inventors might have been on the path to solving the world's energy crisis, and more disappointing still for its recorded distance: 221 feet.
But then again, on their first flight at Kitty Hawk, the Wright brothers didn't do any better. Total distance: 120 feet.
