Listening to "All Things Considered" this afternoon, I decided they really do consider all things. They interviewed two guys who made a video of Diet Coke spewing from 2-liter bottles after chemically reacting with Mentos mints. These guys created a choreographed video with geysers and fountain-like arcs using Mentos and Diet Coke. Funky music in the background fits with the swaying, criss-crossing, explosive routine. It only takes a few minutes to watch. It may inspire you--or your kids--to create some sticky geysers of your own in the back yard on a "boring" summer afternoon:
