Description

Superabsorbent growing polymer water beads that absorb 150 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. Can't get enough of these growing Jelly Marbles? Check out our Jelly Marbles Kit!

We purchased these to use in a mad scientist room located in a middle school sponsored haunted house. They were a great addition to the lesson and to encouraging the students to participate hands on with science. The water swollen balls had great shock value in a fish tank that appeared full of water. Plus it made the students think about the science behind the “disappearing” balls.
