It's Corntastic

Well, I tried a new lab with my Exploratory Agriculture class. We have been discussing corn biotechnology and all of the products that corn helps to make. I thought that making plastic from corn would be a good wrap-it up for the students. 

The plastic is really easy to make. All you needs is cups, spoons, water and cornstarch. Add a teaspoon at a time of water and cornstarch to the cup until the mixture is a thick glue consistency. Pour it into your hand and work it into a ball, but be careful because as soon as you let it go it turns into a liquid! 

This type of liquid is called non newtonian. 

After this lab I showed the Myth Busters video "Walking on Water."
