Mobility Denial System

The Sunday Times Magazine covered a slew of "non lethal wepons" currently in research and / or production here in the US. The Mobility Denial System is a thick goo that when sprayed across any surface makes that surface impassable. It has as much friction as wet ice and therefor can not be walked on or driven over. I love this solution because it's totally effective, totally harmless and draws inspiration from some place between a saturday morning cartoon and a sci-fi novel. via NYTimes
