Oobleck Recipe: Oobleck is a fascinating substance that behaves both like a solid and a liquid. It’s a non-Newtonian fluid, meaning its viscosity changes depending on the pressure applied.
Squeeze it in your hand, and it feels solid; release your grip, and it flows like a liquid. This simple mixture of cornstarch and water is not just a fun play material but also a practical way to explore science.
Why Is It Called Oobleck?
The name “oobleck” comes from Dr. Seuss’s book Bartholomew and the Oobleck. In the story, oobleck is a mysterious, sticky green substance that falls from the sky. While the recipe for our oobleck won’t come from clouds, it captures the same whimsical and messy spirit.
Fun Facts About Oobleck
- Oobleck demonstrates shear-thickening behavior, where it resists flow under pressure.
- It’s named after a fictional substance, but its scientific basis makes it a favorite in classrooms.
- Oobleck has been used in demonstrations to explain earthquake-proofing and even to walk on pools!
