Rubber band experiment.

Objective investigate how the distance of stretch in a rubber band at rest relates to the distance the rubber band travels after being released. The first experiment we show uses the potential energy stored in a rubber band to launch a paper rocket. In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. For this experiment you will need a piece of paper.

I highly suggest doing this watermelon challenge outside as it can make a mess as the name exploding watermelon suggests. The rubber band changes temperature for a different reason 1 than the traditional heat pump but the effect is easy to sense and the test equipment doesn t require a research grant. 1 it turns out that the rubber band heats up and cools off due to the changing order of the molecules in the rubber band and a quantity called entropy but i digress. The rubber in rubber bands is bound together by thousands of long chains of molecules that are coiled together something like a net.
