Video transcript

The ratio of cornstarch to water is typically 2:1. This means you use 2 parts cornstarch for every 1 part water to create a perfect non-Newtonian fluid or thickening agent. Simply mix the two ingredients until you achieve a smooth consistency.

Questions and answers

  1. Why is the cornstarch to water ratio important?

    The ratio determines the consistency and behavior of the non-Newtonian fluid, with 2 parts cornstarch to 1 part water creating an ideal balance for mixing and usage.

  2. Can I use different ratios for varying consistencies?

    Yes, adjusting the cornstarch to water ratio changes the thickness of the mixture; more cornstarch yields a thicker fluid, while more water makes it runnier.

  3. What are common uses for the cornstarch and water mixture?

    This mixture is commonly used as a fun science experiment to demonstrate non-Newtonian fluids or as a natural thickening agent in cooking.
