The purpose of this experiment was to find out how well a stick-em ball stick on a board with a substance or without a substance; and also to find out the effect of different substances. It was hypothesized that the stick-em ball with substance in liquid form such as water would help it to stay longer on the board, because water usually does the best with suction cups. In the experiment, the stick-em ball was thrown onto the whiteboard dipped in a substance and timed for how long it stayed on the board. Surprisingly, the stick-em ball with no substances on it stayed longest on the board, with an average of 385 mins. Another experiment was performed using a spring scale and string to measure how much force is needed to pull the stick-em ball off the whiteboard. It was hypothesized that the stick-em ball with nothing on it would use the most force to be pulled off, because it is really easy to pull off a suction cup with water on it with not a lot of resistance. The stick-em ball with nothing on it needed the most force to be pulled off the whiteboard, with an average of 19.3 Newtons.
 * ABSTRACT **


 * CONCLUSIONS **

Future experiments that could be done are using super magnets to try and pull off a stick-em ball on the white board, using magnets to pull multiple stick-em balls off a white board, or finding out how long stick-em balls can stay on different surfaces, such as wood, plastic, and brick.
