Absorption Classroom Bundle

These growing crystals absorb 300 times their weight in water. You can also color them for amazing results. Use them to introduce students to the environmental benefits of hydrogels, superabsorbent polymers used in items like diapers. They are nontoxic, so your students can get their hands right in them. When the experiments are done, let the water crystals dry out and use them again for future science fun.

These polymer orbs are squishy and bouncy, but no matter how often they absorb and lose water, they never lose their colors. Use them for science classification projects, as math counters or as a prop in any cool science experiment. Includes a Count and Classify worksheet.

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.

Jelly Marbles are an example of amazing hydrogels
Hyrdrogels are superabsorbant 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.

Fun For Anytime of the Year, Especially Halloween!
Unsuspecting Trick-or-Treaters will be surprised when they place their hands in a bowl of ooey, gooey “eyeballs”! Perfect for any Halloween party!

Watch Them Grow To the Shape of One of Our Baby Soda Bottles
Your young scientists will be surprised to see that the marbles maintain their spherical shape. Not only do these clear spheres absorb water, but they also absorb color to make them even more interesting!

Reusable Science Toy for Kids!
Steve Spangler’s Jelly Marbles can be used over and over again! Try drying them out to see how quickly evaporation can take over, and then drop them in water and watch them grow again and again! The included Activity Guide teaches you all the science behind this amazing polymer!

Though small at first, these polymer cubes can grow to more than 200 times their original size when they absorb water. Your students can make geometry connections by measuring shapes as well as chemistry connections as they learn about the science of polymers through this cool science experiment.
