Water Cube Kit

Can’t get enough Water Jelly Crystals? Crazy for Clear Spheres? Well, our never-tiring Polymer-ologists have searched high and low to bring you the newest polymer sensation... Polymer Cubes. This tiny, squishy cubes CAN grow over 200 times their original size when you plop them in water and they help make the connection between math and science with a unique look at geometric shapes. We'll even throw in a Cube Growing Sheet to help you track the growth of your cubes... from tiny to tremendous. Once you “grow” these water-filled cubes, you won’t be able to put them down! Recommended for children ages 6 and up.

What Does It Teach?

Like all of our fun and fascinating polymer products, these tiny cubes, teach a big lesson... in math, chemistry and the importance these thirsty cubes can play in maintaining a healthy environment. The possibilities for experimentation are endless when you drop these cubes in water. Try drying them out to see how quickly evaporation can take over… and then use them again and again. The included activity guide will guide you through making the math and science connection.

Customer Reviews

Always a hit Review by Mom

When my daughter shares these at school they are always a hit. Steve Spangler offers so many shapes, but the big ones are the most fun. Thanks Steve! (Posted on 5/22/13)

Cubes and Spheres are my favorite products Review by Jenny Brown

These and the polymer spheres are my favorite Steve Spangler products. I recently used the spheres as a visual aid for a teen fall retreat and the students almost came up out of their seats they were so surprised. After the lesson they rushed the stage to see them up close. They loved playing with them and of course they all wanted to know where I got them. Thank you Steve Spangler for these amazing products.
