  • Polyacrylamide Gel Crystals - Home Science Tools

    Water gel crystals, also known as water jelly crystals and superabsorbent polymer, are able to absorb up to 400 times their weight in water. Place 1 teaspoon (4g) of these small 2-4mm crystals in a quart of water, let it sit overnight, pour off the excess water and you will have over 2 cups of beautiful, large 1-2' jelly-like clear crystals.
