It took us two years of testing, but we found the world’s best growing alligators! Then, we tweaked the polymer formula and made these growing gators even better. These little buggers are so good that we even supply them to other science companies.
The gator starts out only 11 centimeters long (4.5 in). Place the creature in water and watch it grow to an amazing size of almost 41 cm (16 in) long.
See the Growing Creature Science Project to learn how to use this simple science toy to create a great science fair project.
Recommended for children ages 4 and up.
How Does It Work?
Growing creatures are made out of a superabsorbent polymer that soaks up water. The polymer is similar to the non-toxic chemical used in baby diapers. Don’t overlook the educational value of these inexpensive toys.
What Does It Teach?
Discover how thirsty polymers perform very important functions in everyday life. They’re used in everything from baby diapers to environmental cleanup materials! Aside from their environmental and industrial uses, discover how different kinds of polymers help these “growing toys” keep their shape as they expand.
How big do they get?
They grow to an amazing 40 cm (16 in). That’s about 4 times their original size!
How do they compare to your giant creatures?
These large growing gators don’t start out as large as the ginormous creatures, so they don’t grow quite as large either.
