Do Liquid Objects Travel Farther than Solid Objects when Thrown?

Overview

Objectives/Goals The success of this project depended on building a catapult, with the help of a parent. Using algebra to calculate the system of weights, and levers needed to throw a water balloon the optimum distance. Then make 28 water balloons that were the same size and weight. Freeze three of them and flung them one after the other. Methods/Materials On average, the frozen water balloon went as much as 9 feet farther than the unfrozen water balloon. Results This happened because as the liquid water balloons flew threw the air they changed into a shape with a lot of resistance. Conclusions/Discussion The intent of this science fair project is to find out whether liquids could cover a larger distance than a solid object when thrown with equal force.
