- Penguins Hatch'ems Egg Grow in Water Toy
)
Product Description
Kids will love hatching their very own penguin with this Hatch'em grow in water toy. Just add water and watch as the egg gradually cracks open over a period of 48 hrs. to reveal a penguin that grows to over 3 times its original size!
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?
