I highly suggest doing this watermelon challenge outside as it can make a mess as the name exploding watermelon suggests. When you pull a rubber band the molecules uncoil and align themselves closer together as they straighten out. 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. When the rubber band is heated heat energy from the surrounding environment goes into the molecules of the rubber band and causes them to vibrate.

The work performed by your heat engine in this experiment is the movement of the weight by the expansion and contraction of the rubber band. Anything attached to the rubber band may be flung forwards or upwards with the force of this energy. The rubber in rubber bands is bound together by thousands of long chains of molecules that are coiled together something like a net. 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.
