 * THE STUDY OF RUBBER BANDS AND THEIR VARIABLES**

The purpose of this study is to determine whether or not variables effect the length the rubber bands can be stretched, launched ,or launching an object. Rubber bands are made of long tubes of rubber that have been narrowly cut. In this study rubber bands were dipped in many different liquids to determine if it made them any more elastic, rubber bands were also put at different temperatures, launched ,and had objects launched from them, and the experiment was concluded by testing the fingers a rubber band was launched from. It was found that if a rubber band is in any type of liquid its elasticity will improve, and that some types of fingers are better for launching than others. The rubber bands stretched were more elastic when being soaked in liquid because the molecules in the water loosen the rubber band making it more elastic, and some fingers are better for launching than other because of control.
 * ABSTRACT**

An improvement to this experiment would be to use a actual timer instead of a clock for the time spent soaked because timers are more percise then a clock. A a follow up experiment for this would be if the pH of a liquid can effect the rubber in.
