Gizmodo has a link to a Youtube video on non-newtonian liquids [gizmodo.com] and how they react to various impacts when viewed with a high speed camera:
The Backyard Scientist went and filled up balloons with non-Newtonian fluids and ripped a chainsaw through them, shot a BB-gun at them, and fired off a golf ball cannon at them too.
He wanted to compare how non-Newtonian fluid would react vs regular ol’ water in the same situation.
The fluid in question is Oobleck [wikipedia.org]
