Slime, Peter Venkman Style

It may not be a positron collider, but researchers at the Southwest Research Institute have come up with a portable, Ghostbusterlike device that allows the wearer to cover the ground in slippery goo. The purpose? Non-lethal crowd control.

The backpack system, which weighs less than 75 pounds, can shoot a non-toxic material up to 25 feet. The goo is so slippery that it's almost impossible for a person -- or a car, for that matter -- to maintain their traction.

A little while ago, Hit and Run's Brian Doherty brought us the early development and full patent info for the device. You can now see a picture of the nostalgia-inducing apparatus here.
