575010 OOZE LABS 10: QUICKSAND OOZEBLECK

Magnetic Slime science kits.

Mix your own oobleck — a mysterious oozy substance that behaves a little like quicksand. It becomes a rigid solid under force, but runs like a liquid when no force is applied. This classic science experiment teaches about the unique properties non-Newtonian fluids — fluids that can act like a solid or a liquid depending on how much force is acting upon them.
