Kate's Corner: Mystery goo

By  | 

BRIDGEPORT. W. Va. (WDTV) - In this Kate's Corner we are going to make our own unique goo!

Here's what we'll need:
- Water (about 1/2 to 1 cup)
- Cornstarch (about 2 cups)
- Food coloring (optional)
- A big bowl

n a bowl we are going to add some corn starch and half a cup of water. Keep adding water water and corn starch until you get the right consistency. You'll want it to be the consistency of honey.

I'm getting messy and using my hands to mix up our goo.

One major clean up tip: do NOT put this goo down the drain.

You'll notice as you mix the two together that sometimes it acts as a liquid and other times it acts like a solid.

Try making a ball. Its easy but the moment I stop applying pressure to the goo, it's back to a liquid.

So what is this substance? A liquid or a solid? Well, its called a non-newtonian solution. Which means it doesn't act the way Isaac Newton said a solution should act.

When you apply force to the goo, you force the long starch molecules closer together. The impact of this force traps the water between the starch chains to form a semirigid structure. When the pressure is released, the cornstarch flows again. That is why you go so quickly from a solid feeling solution to a liquid one.
