oobleck

Non-Newtonian kitchen concoction

Oobleck is a mixture of cornstarch and water that behaves as both liquid and solid—it flows when handled gently but resists sudden force.

Named after a sticky substance in a Dr.

Seuss book, it's a classic science demonstration of non-Newtonian fluids: The kids made oobleck and watched it ooze through their fingers, then harden when punched.
