We know you love our Jelly Marbles and our Water Cubes... why not love them even more when we put them together in this Jumbo Test Tube Kit? We'll even throw in some coloring tablets to make a rainbow of growing polymers! These superabsorbent polymers will leave you amazed as they grow up to 300 times their original size when you put them in water... and when you are ready just take them out of the water, let them shrink back down and use them again and again! Recommended for children ages 4 and up.
- 2 Jumbo Test Tubes with Rack and lids
- 10 grams of Jelly Marbles Polymer
- 10 grams of Water Cubes Polymer
- True Colors Color Mixing Tablets
What does it teach?Like all of our fun and fascinating polymer products, these tiny cubes and marbles teach a big lesson... in math, chemistry and the importance these thirsty polymers can play in maintaining a healthy environment. The possibilities for experimentation are endless when you drop the polymer in water. Try drying them out to see how quickly evaporation can take over… and then use them again and again.

My grandchildren (ages 7, 10 and 13)loved these. They played and played with them. It was so fun to make a hypothesis about what we thought would happen with the colors when they dehydrated. The reason I only gave them 4 stars is because they are a little fragile and we had a few of them break on us. One was dropped and another just split open while it was dehydrating. They handled them a lot as they watched them change. My 7 yr old grandson, who is not really into science, was fascinated and asked to take them to school for show and tell. Would recommend them!
Thank you, thank you, thank you!!
