What is an oobleck? Oobleck is a non-Newtonian fluid. In other words, it's a liquid that sometimes acts like a solid, such as quicksand. Tap it fast, and it feels hard. Poke it slowly and your hand sinks right in.
Create your own Oobleck with this powder - then dry it out and reuse it again!
Our Oobleck glows under black light and is a special mixture of powders created to replicate real quicksand. The texture will blow your mind. Simply adding water turns the powder into a goo that can be both a liquid and a solid.
Nontoxic and antibacterial, but the colors can stain hands, wash off with mild soap and water.
