Mainers make 'rocket car' with Mentos, soda

BUCKFIELD, ME The contraption created by Fritz Grobe and Stephen Voltz of Buckfield features a utility trailer on the back and a modified girl's bike at the front.

They're offering a teaser of their invention on their website. The full video directed by Rob Cohen of "The Fast and the Furious" will debut online Tuesday.

Grobe tells the Sun Journal newspaper that their latest invention uses Coke Zero and has been dubbed "The Fizzy and the Furious."

The two, dressed in lab coats and goggles, became Internet celebrities four years ago with their "experiments" that created geysers by dropping Mentos candies into bottles of Diet Coke.
