Swell Polymer Sperm Whale - Grow in Water Toy
Product Description
This accurate model of a sperm whale will grow many times its size when submerged in water.
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?
- Recommended for ages : 8 to 13+.
