You've surely seen the Diet Coke and Mentos rockets that have been all over the Interwubs for the last couple of years. For those who haven't, a pair of intrepid scienticians demonstrated that dropping Mentos mints into diet cola causes a chemical reaction that shoots the foamy concoction out of the coke bottles in a fountain-like manner.
The same pair, who've been making the rounds at Maker Faires and other DIY events, this week posted this video of a custom tricycle-type vehicle that works along the same principle. It uses a piston drive to harness the power of 108 two-liter bottles of Coke Zero and 648 Mentos to propel the vehicle more than 200 feet.
Sure, it's not the fastest ride in the world, but we think this is a video of a Wright Brothers-like moment in science. In the near future, we'll all be driving around in eco-friendly Coke Zero-powered vehicles, leaving nothing but clean, tasty sugar substitute as a byproduct.
