Jelly Marbles - Clear Spheres (50 gram jar)

Superabsorbent growing polymer water beads that absorb 300 times their weight in water and grow into a perfect sphere that looks like a water marble. Place these tiny, solid spheres in water, and in just a little while you will have your own Jelly Marbles. These superabsorbent water marbles are the newest craze around the Spangler Science offices! What starts out as a 3mm pebble, quickly becomes an approximately 20mm ball of jelly! Similar to our Water Jelly Crystals , these water beads absorb a lot of water, plus they maintain their spherical shape when they are done growing. Not only are these superabsorbent marbles fun, they teach a valuable lesson about the power of polymers. In fact, Jelly Marbles are an example of amazing Hydrogels... superabsorbent polymers that are saving the environment. Whether you think they look like water marbles, water beads, or clear spheres, you'll want to get your hands on these squishy, water-filled Jelly Marbles.
