Place these tiny, solid spheres in water, and in just a little while you will have your own Jelly Marbles. These superabsorbent 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 Jelly Marbles 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.

What does it teach?

Like all of our fun and fascinating polymer, or Hydrogel, products, these tiny spheres, teach a big lesson in color, light and the importance these thirsty pebbles can play in maintaining a healthy environment. The possibilities for experimentation are endless when you drop these spheres in water. Put them in one of our Baby Soda Bottles and they grow to the shape of the test tube. Try drying them out to see how quickly evaporation can take over… and then use them again and again. Plus, you can only imagine the fun to be at the Spangler Science offices when Halloween rolls around... imagine the surprise when unsuspecting trick-or-treaters place their hands into a bowl of ooey, gooey, “eyeballs!”
