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.
