Question: Can a case filled with
non-Newtonian fluid support my weight as I run across its surface or step on? How does viscosity affect fluidity?

Hypothesis: A case filled with non-Newtonian
fluid (Mixture of water and starch) can support my weight.
fluid (Mixture of water and starch) can support my weight.
This experiment you will need:
- Corn starch
- water
- Food coloring
- a case for mixing (Huge enough to step in)
- Towel/ tissue/ newspaper (you don't have to prepare all of these)
1. Pour water approximately 1/4 of
case (deep enough to sink your feet) then pour starch several bags of starch.

2. Keep stirring it as adding
starch and water in small amounts until you get a mixture similar to honey.

and move your hand around slowly and then very quickly. If you can’t pull your
hand out from the mixture as you pull your hand very fast, it’s done!
4. Try to grab the fluid, step on
it, run across it… Have Fun!

thickness or resistance to flow of this mixture is high. The fluid
could support my weight which means that the visocisty of this fluid is high enough to handle a human's weight.
