Jelly Marbles™ At-Home Science Experiment
You Won’t Believe Your Eyes
These Jelly Marbles are clear when submerged in water and grow almost seven times their size. Place these tiny, solid beads in water and in just a short time, you will have Jelly Marbles that absorbed over 150 times their weight in water. These superabsorbent water marbles are the newest craze from Steve Spangler Science.
What begins as a 3-millimeter pebble quickly transforms into a 20-millimeter ball of jelly. Just like our Water Jelly Crystals, these water beads absorb a lot of water while maintaining their spherical shape. Not only are these superabsorbent marbles fun, but they also teach a valuable lesson about the power of polymers.
Jelly Marbles Are Amazing Hydrogels
Hyrdrogels are superabsorbent polymers that are being used to save the environment. You’ll want to get your hands on these squishy, water-filled Jelly Marbles to teach young scientists about the amazing potential of polymers.
What can we learn from Jelly Marbles?
Like all of our fun and fascinating polymer and hydrogel products, these tiny spheres teach a big lesson in color mixing, light refraction and the importance hydrogels can play in maintaining a healthy environment. The possibilities for experimentation are endless once 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!

The Wonder of Hydrogels
Young scientists of ages six and older will have great fun with the Jelly Marbles Test Tube™ Kit from Steve Spangler Science. The beads of three-dimensional, cross-linked polymer networks love to absorb water and young scientists will love to play with them. Hydrogels have a huge number of applications in modern science and this experiment kit will inspire kids to pursue to wonder of science throughout their lives.
The way children learn about science will influence their future interest in it, and conducting the three experiments included in this kit will impress upon them the importance of chemical creations like polymers. As the young students watch the small spheres absorb over 150 times their weight in water, you can help them understand how hydrogels can remedy droughts, aid in wound healing and many other scientific and medical applications.

Question
R M –
About how long does it take for them to reach full size once they are put in water?

Our Jelly Marbles take 8-10 hours to fully hydrate and absorb all the water they can. We suggest letting them sit overnight to get to their full size.
