Stephen Voltz And Fritz Grobe discovered an amazing reaction between Coke and Mentos . A while back they posted the video of their experiment on the internet . Their video spread much more quicker than the reaction between Coke and Mentos !. The film has been viewed more than 6 000000 times . Mentos approached the two geyser freaks and asked for their collaboration on a project . They decided to launch a geyser contest . A special website was created by Mentos where participants were required to send a video of their experiments . The project was a huge success . Now the two geyser freaks are back with something more original . But this time they are collaborating with Coke .
A free advertising campaign for both Mentos and Coke initiated by two customers !!!
