While researching a topic, a student has taken the following notes:
- The typical resting viscosity of oobleck (cornstarch mixed with water) is 5–100 centipoise (cP).
- Oobleck increases in viscosity (becomes thicker) when squeezed.
- The typical resting viscosity of cake frosting is 2,000–10,000 (cP).
- Cake frosting decreases in viscosity (becomes thinner) when squeezed.
- A fluid is Newtonian if its viscosity remains stable under shear (mechanical force such as being squeezed or stirred).
- A fluid is non-Newtonian if its viscosity changes under shear.
