On this episode of Scientific Tuesdays, Dylan shows you how to create a non-Newtonian fluid using corn starch and a little water. A non-Newtonian fluid is any fluid that does not follow the laws of physics.
- Measure out 1/2 cup of 100% corn starch with a measuring cup and pour it into a bowl.
- Measure out about 1/4 cup of water and add it to the corn starch.
- Mix the substance slowly with a fork or spoon, making sure the substance is thickening.
- Once you're done stirring, grab the liquid with your fingers and roll it around in your fingers. The mixture should stay solid between your fingers as you're rolling it, and turn back into a liquid as soon as you let go of it.
You can test your liquid by pouring it into a water-sealed speaker. Playing a high enough frequency sound allows you to see some of the cool effects of this liquid.
