They Never Lose Their Amazing Color!

These multi-colored spheres are like jelly marbles!

I’m sure you’re thinking that after we brought you Jelly Marbles, Water Spikes, Water Cubes, and Water Jelly Crystals, we couldn’t possibly have another superabsorbent polymer up our sleeves… well, think again! Just when you thought polymers couldn’t get any cooler, let us introduce you to Colorful Growing Orbs! These multi-colored spheres are much like Jelly Marbles, but they never lose their amazing color!

For teachers, parents, grandparents & 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 into real thinkers! Look what your young scientist integrated into the Colorful Growing Orbs activities.

How does it work?

These tiny orbs teach big lessons in color, light, and the importance that these thirsty pebbles can play in maintaining a healthy environment. Try drying them out to see how quickly evaporation can take over — and then use them again and again.

Shrinking and Expanding Orbs

Children of age six and up can feel like they are real scientists when they get to work with the Colorful Growing Orbs Test Tube Science Kit from Steve Spangler Science. The magic of hydrogel polymers comes alive when they put the tiny orbs into water to soak for several hours. As they grow bigger and bigger, the young scientists will learn to appreciate how important hydrogels are for helping the environment in areas where conservation of water is needed. Seeing real-life demonstrations like these expanding and shrinking colorful orbs give children the inspiration they need to learn about physical and chemical properties of matter and the desire to choose STEM courses as their electives when they reach higher levels of their education.

The Possibilities for Experimentation Are Endless…

Just drop the Colorful Growing Orbs in water to soak. Put them in one of our Baby Soda Bottles and observe how they grow to the shape of the test tube.
