 * TESTING THE BOUNCABILITY OF BOUNCY BALLS SOAKED IN LIQUIDS **


 * ABSTRACT **

The main purpose of this experiment was to find whether liquids affected the height a bouncy ball normally bounces. It was hypothesized that the normal bouncy ball would bounce the higher than the balls soaked in vinegar and water. To perform the experiment, the bouncy ball was dropped from the top of a meter stick, 100 cm, and the heights they rebounded were recorded. Each ball was bounced a total of three times to get results that were more accurate. The other balls were soaked in beakers filled with vinegar and water for 15 seconds, at separate times, and then bounced to compare their heights to the normal ball’s. It turns out that the hypothesis was correct and the bouncy ball soaked in nothing bounced the highest out of all three. The vinegar-soaked ball bounced the least and the water-soaked ball bounced in the middle of the other two.

To make this experiment better, more trials could have been conducted to get results that were more accurate. This experiment could also have been tested with different types of ball, like ping pong balls to see if that made a difference in the height. The vinegar and water might affect the ping pong balls because they are lighter than bouncy balls.
