These 1" long, 1/4" thick clear, colorless spikes are made from a super-absorbent, polyacrylamide polymer similar to our Water Gel Crystals. When placed in water they expand to several inches with a corresponding gain in mass as they absorb water. They are great for quantitative measuring experiments. Water Gel Spikes are made from a cross-linked polymer and stand up to student use. (10 spikes per package.)

Growing Cubes

Same hydrophilic polymer, but made into different cubic shapes that can be stacked. 50 grams (approx. 290 cubes)

Growing Spheres (Three Sizes)

Place these hard crystals in water and they expand about 300 times, producing gel-like spheres. Now available in three sizes.

Water Gel Animals - While Supplies Last

These small colored bumblebees don't grow quite as large as the Gro-Beasts but stand up to student use.

Water Gel Crystals - "Ghost Crystals"

Placed in water these crystals absorb many hundreds of times their own weight and become virtually invisible.
