You Won’t Believe Your Eyes!

These Jelly Marbles become invisible when submerged in water but grow almost 7 times their size!

Just add water and discover the magic! Place these tiny, solid spheres in water, and in just a little while you will have your own Jelly Marbles that absorbed over 150 times their weight in water. 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.

Fun With Superabsorbent Water Marbles

Young students can learn about the power of hydrogel polymers and have fun at the same time with the Jelly Marbles™ Starter Set from Steve Spangler Science. Hydrogels are extensively used in many industries and have a wide range of applications in the modern world. These useful polymers are made of three-dimensional networks of cross-linked molecules. These molecules can absorb enough water to make them as much as 150 times their original weight. Since hydrogels occur naturally, artificial ones made from polymers are often biocompatible and can be used to heal wounds. The Jelly Marbles™ Starter Set includes an activity guide with instructions for five different experiments that will fascinate children and nurture their interest in polymers and chemistry.

Jelly Marbles are an example of amazing hydrogels

Hyrdrogels are super absorbent 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.

What does it teach?

Like all of our fun and fascinating polymer, or hydrogel, products, these tiny spheres, teach a big lesson in color mixing, light refraction, 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.
