Product Description

Fill your aquarium with sea creatures you grow yourself! Simply place the sea creature in a container of water and watch it grow up to five times its original size within four days. For extended fun you can dry them out and grow them again and again. Each sea creature comes with comprehensive instructions.  

Styles vary - use the selection option when placing your order.  Collect them all!

Grow in water toys are made of special super absorbent polymers similar to the non-toxic chemicals used in baby diapers.

To conduct some fun science experiments, change a variable when you are growing your critters, ie.

  • tap water vs. distilled water
  • what happens if you use salt water
  • water temperature
  • how long does the water take to evaporate – do temperature and humidity affect it?

Ages 5+
