 * DOES THE TYPE OF LIQUID A SPITBALL IS SOAKED IN EFFECT THE DISTANCE IT FLIES **

The purpose of this study was to inform the reader of projectile motion, how forces can effect an objects’ flight path, and how the weight and mass of a projectile can effect its’ flight path. It was explained how the angle a projectile is fired at can affect its’ flight path and what projectile motion is. In the most important experiment spitballs were soaked in orange juice, 2% milk, water and salt water for ten seconds, then they were shot out and the distance was measured. When soaked in orange juice the spitball flew the farthest, going 409.83 cm, and flying the least distance when soaked in water, going only 279.63 cm. This was because when a liquid has a high viscosity, it is heavier and thicker, being able to put more force behind it, but when the liquid has a low viscosity the liquid doesn't make it heavy enough, and does not fly as far because it is more difficult to keep a light object moving at a constant speed.
 * ABSTRACT **

**EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS** Future experiments on this topic that could consist of does the amount of time a spitball s soaked in water effect the distance that the spitball flies. Another future experiment that could be done is does the type of straw effect the distance a spitball flies. Something that could have been improved the during the experiment phase was how efficiently the experiments were done, they were done with lots of care and precaution but not done quick enough. It would have been nice to have more experiments completed with more results that showed trends so that something could actually be proved from the results.
