Water Jelly Crystals

Just add water and watch them grow.


Just add water and watch them grow. The white pebble-like crystals absorb tremendous amounts of water... like a water-slurping sponge. These so-called Water Jelly Crystals are actually classified by scientists as a superabsorbent polymer. Water Jelly Crystals can soak up to about 300 times their weight in water! Today, Water Jelly Crystals are being used to hold water in the soil so it can be released to plants as they need it, and they can help reduce watering demands of plants by up to 80% in drought conditions. That's water-saving science!
