Last year (2013-14) my General Chemistry class was studying states of matter. I decided to extend their thinking by having them make oobleck.  They had fun playing in the science and trying to decide if it was a solid or a liquid.  Depending on how it’s handled it can be both. After they did the experiment we watched the video below where Adam and Jamie of the Mythbusters tried to walk on water.

After we finished watching the video they all said “Can we do that?” And so after buying a kiddie pool and 150 pounds of cornstarch this is what we ended up with. Enjoy. The students did.
