Product Description

Grow your very own pet hermit crab!  Just put in water and watch it grow!

As the crabs grows, so too does your child’s interest in science and nature. Place the crab in a container of water. In the following 72-hour period, the crab will expand up to six times its original size! The crab will revert to its previous size so you can grow it again and again.

Hermit crabs sold individually.  Colors will vary.

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+

Warning: CHOKING HAZARD - small parts. Not for children under 3 years.
