BUCKFIELD, Maine -- The Maine guys known for creating colorful geysers from Diet Coke and Mentos candies say they've set a distance record for a vehicle with soda-and-candy-powered propulsion.
Fritz Grobe and Stephen Voltz created a single-seat rocket car powered by 54 bottles of Coke Zero and 324 Mentos. They say the Mark II traveled 239 feet, improving upon last year's 220 feet with only half the fuel. They posted video of a 209-foot attempt online.
Voltz said Thursday they incorporated a simple piston-and-cylinder mechanism to get the vehicle moving. He says it's powerful enough that people shouldn't try the experiment at home.
The Buckfield-based entertainers shot to fame five years ago when they wore lab coats and goggles during their online videos demonstrating elaborate geysers set to music.
