• copernicus swell polymers growing sperm whale

Swell Polymers are a fun activity that provides an educational experience for kids who are fascinated by science! This Sperm Whale is a growing super absorbent polymer that will grow to be 100 times larger than its original form. Simply submerge this amazing creature of the seas into water and watch it grow! It may take a week for this awesome beast to reach its full size and the Sperm Whale will shrink over time when out of water. Recommended for ages 8 and up this polymer animal is the perfect stocking stuffer for the budding Jacques Cousteau in your life!
