Just drop the alligator or another creature in water and watch it grow!
Have you ever wanted your own pet alligator, but just didn’t think it would work in the classroom or in your bedroom? Try this experiment and watch as these tiny creatures grow 5 to 10 times their original size… maybe more… once you drop them in water. These growing wonders are made out of a special superabsorbent polymer that soaks up water. The polymer, or hydrogel, is similar to the non-toxic chemical used in baby diapers. So, don’t overlook the educational value of these popular toys.
