Gro Beasts - Polymers

Gro Beasts are some of our most popular products. They are fantastic for any grade level, and affordable enough to hand out to every student in your class! The Large Gro-Beast Alligators start at about 3 inches long and grow to over a foot long when placed in water! When placed in water the Small Gro-Beast Dinosaurs expand by about 600%! When placed in water, Water Gel Crystals - or "Ghost Crystals" - absorb many hundreds of times their own weight and become virtually invisible. Place Growing Spheres in water and they expand about 300 times, producing gel-like spheres. Now available in three sizes, plus a Gigantic size! We also carry growing cubes and spikes.
