Exploding WatermelonRead Now
One of my Twitter followers named Ken has a You Tube Channel called Kid’s Fun Science where he posts the science experiments that he conducts during Science Night at his local Elementary School. In the video below he shows the blowing up of a watermelon employing rubber bands using the potential energy accumulated in rubber bands after stretching them around the melon.
There are several forms of potential energy. The potential energy stored in an stretched rubber band is called elastic potential energy. This type of potential energy can be stored in elastic materials as a result of stretching or compressing and can be converted very rapidly into kinetic energy (energy of movement) when the force opposing the compression or stretching (in this case the structural integrity of the watermelon) is eliminated. Check out at the end of the video the final fate of the rubber bands after the release of their pent-up energy!
I encourage you to check other fun science experiments in the Kid's Fun Science You Tube Channel and to follow them on Twitter, Facebook, Instagram, and Pinterest.
