Watch this video about the Mentos Coke world record on HowStuffWorks. Mentos(R) and the performance artists of Eepybird have made Mentos Geyser history in Cincinnati with a big splash. Eepybird, with the help of 504 Greater Cincinnatians equipped with the new "Mentos Geyser Loading Tube," launched the largest number of Mentos Geysers ever to be set off all at once in one location, setting a world record.
