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 spheres 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.
