This Summer, Unleash the Power of Diet Soda

Americans have a new way to celebrate the Fourth of July: Drop Mentos candies into 2-liter bottles of Diet Coke and watch as the soda shoots skyward.

For the messy technique, thank Fritz Grobe and Stephen Voltz. The two performers from Buckfield, Maine, appear in a three-minute Internet video in which they don goggles and lab coats and show the world how to create the geysers. The resulting 20-foot blasts have captured the imagination of millions.
