What is Oobleck?

Oobleck is a fun non-Newtonian fluid that can change its consistency based on the amount of force applied to it. You can make oobleck with baking soda, despite it being traditionally made with cornstarch.

A non-Newtonian fluid is a type of liquid that doesn’t behave like most liquids. Most liquids flow easily and their consistency doesn’t change much when you apply force to them.
