All About Oobleck
Oobleck was named after a material in a Dr. Seuss book. Oobleck is created when you mix corn flour or cornstarch together with water. This creates a fluid slime like material that is known to not follow Sir Isaac Newton’s laws of fluid. If you put stress on Oobleck, it will turn into a solid. If you move your hand slowly through it, then it feels like moving your hand through water. This happens because when you hit the Oobleck hard and fast with things like your hand, the particles of the corn flour or cornstarch packs together making it a temporary solid. When you move your hand slowly and gently throughout the Oobleck, the particles have time to move out of the way allowing your hand to pass through like water.
