Our Shimmer Putty Trio is a trifecta of scientific awesomeness! It bounces like a super ball, flows like slime, shears when pulled... and it sparkles! Each plastic jar contains three different colored portions of slippery, shimmery, scented, silicone-based putty. Introduce your students to non-Newtonian substances and let the learning begin! Why is it so cold? What happens if you mix the colors together? Is it a solid or a liquid? Colored layers are separated by plastic caps which can be kept or discarded. Colors may vary.
