Make Your Own High Bounce Ball

The bouncy ball granules are mostly composed of polyvinyl alcohol (PVA), which is a water-soluble polymer with elastic properties. Polymers are long, tangled chains of carbon, hydrogen, and oxygen atoms. When the granules are moistened, their surfaces start to dissolve slowly, they swell up a little, and they become sticky. The long polymers get tangled up in each other. In this way, the granules stick together inside the mould. The balls are bouncy because the PVA material is elastic, which means it springs back to its original shape after being compressed or stretched. (12853)
