100 Days Project

Nanogirl: Star Science

Nanogirl wants to find 100 friends to do science experiments with her to prove that no matter who you are or what your education level, you can always have fun with science.

Day 19:

Maddy and Allie show me Non-Newtonian fluids

Maddy and Allie are both 13 and today we learned about Non-Newtonian fluids. 

By mixing corn flour and water together we made a fluid that didn't behave like you would expect it to.

Non-Newtonian fluids change the way they flow depending on the speed of the force you apply. If you apply a fast force (the girls punched the fluid) then it gets thicker and seems to be solid when you punch it. If you apply a slow force for example letting your hand sink into it or allowing it to flow from your fingers back into the plate, it runs just like a normal liquid.

This is very different to a Newtonian fluid such as water that would just fluid like if you punched it or poured it.
