What is Oobleck?
Oobleck is a non-Newtonian fluid; it has properties of both liquids and solids. Its pressure dependent – You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid.
The name oobleck comes from the Dr. Seuss book, “Bartholomew and the Oobleck.” In the story, oobleck, a gooey green substance, fell from the sky and wreaked havoc in the kingdom.
Oobleck makes a great science project or simply have fun playing with it, like us. 😀
