Physical Science Fun

GCA'S Physical Science class was charged with doing a presentation and demonstration of a colloid.  Jeb Smith selected an Oobleck mixture of cornstarch and water.  

The students enjoyed the gooey consistency; however, by adding a strong force with high speed it turns into a solid.  In the picture you see the students enjoying the liquid side of the Oobleck, but then Jeb put the tub on the floor and added his force and speed. 
He was then able to run on it. 
Cool, crazy fun!
