We all know that slime is cool, but this slime is REALLY cool - literally! You'll marvel at how chilly this stuff is. Each flask contains colorful, shimmery goo that breaks when you pull it apart, but also flows like a liquid. Ask students, why does it feel so cold? Is it a solid or a liquid? An awesome discrepant event demo that you can relate to many topics: heat energy, non-Newtonian fluids, polymers, and so much more. Comes in assorted colors.
