A little more about Jelly Marbles™
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.

For Teachers, Parents, Grandparents, and All-Around Science Adults!
We haven’t forgotten about the new STEM and STEAM initiatives you’ve been hearing about in our schools, bringing Science, Technology, Engineering, (Art), and Math together to make young scientists real thinkers!
Make a STEM Connection!
Let’s work together to inspire the next generation of scientists and engineers. At Steve Spangler Science, STEM is not just an acronym or a checklist of required subjects (science, technology, engineering, and math). Our STEM products encourage young scientists to create new and exciting experiences that foster the skills of collaboration, communication, critical thinking, and creativity.
What does Jelly Marbles™ 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.
