Another science experiment/project. Mentos in Diet Coke.
Carrie built a delivery mechanism for the Mentos (a curled up piece of paper to fit inside an open soda bottle top). The boys carefully placed the Mentos in the ammunition cartridge, then dropped the charges into the soda. The blast of fizzing soda went about 6-10 feet in the air. Over my head, and way over the boys heads. Note the boys faces. See movie below.
