These experiments were performed to determine if and how a Diet Coke and Mentos geyser could be made into a squirt gun. The original experiment was testing different sizes of Diet Coke to see which produced the best geyser. It was hypothesized that the squirt gun would be able to be made with a 2-liter bottle held at 120 degrees away from the body, but when transferred to a new bottle, the Diet Coke would not produce a geyser. The Geyser Tube was attached to the Coke bottle and the Mentos loaded into it. The string on the Geyser Tube was pulled and the geyser shot up. The 2-liter bottle produced the best geyser. Two extension experiments were also performed, one of which was to test what angle the squirt gun should be held at to produce the best geyser. The soda bottles were held at different angles and the original experiment preformed. When held at 120 degrees away from the body, the shot went the farthest. The last experiment was a relationship experiment testing whether or not Diet Coke would produce a geyser when poured into a new bottle. The experiment was performed by pouring all of the Coke out of one 2-liter bottle and into another and performing the original experiment. The experiment worked, but the geyser was lower. It was concluded that a Diet Coke and Mentos geyser could be made into a squirt gun, but only under the right conditions.
 * ABSTRACT**

One future experiment that could be performed would be to engineer a specialized squirt gun for this purpose. Another experiment to extend the experiments done would be to use different flavors of Mentos and see if they affected the geyser, or to break the Mentos in half to see if that affected the squirt gun.
