Watch These Little Spheres G-r-o-w Right Before Your Eyes!

This kit of small, clear spheres can teach your students about polymers, color mixing, and light refraction. Once you put the tiny spheres in water, your students will be amazed at how these marbles can grow to almost seven times their original size, from 3mm to 20mm. Your young scientists will also be surprised to see that the marbles maintain their spherical shape. Not only do these clear spheres absorb water, but they can also absorb color to make them even more interesting. The kit comes with color mixing tablets and mixing trays to make this cool science experiment happen.
