500 Greater Cincinnatians equipped with bottles of Diet Coke and a roll of Mentos set out to launch the largest number of Mentos Geysers ever to be set off all at once in one location. Drum roll please… and the first ever Mentos Guinness World Record for “Most Mentos and Soda Fountains” goes to a large crowd of wet people in Cincinnati. According to the press release, each of the 500 participants were given nice goody bag stuffed with candy, a Mentos geyser loading tube, goggles and a rain slicker. The loading tube they used is similar to the Geyser Tube but there’s no build-up of pressure like the real Geyser Tube. The guys from Eepybird (the lab coat and goggle wearing guys who created that cool video on YouTube) entertained everyone with a few of their cool choreographed displays and then they led the big count down.
