New Scientist Invention blog: Riot slimer

New Scientist Invention blog: Riot slimer
Rioters could soon be in for a slippery surprise. Researchers at the Southwest Research Institute in San Antonio, Texas, US, are working on a new non-lethal weapon that could quite literally bring them to their knees – by sliming them.

The institute has developed a super-slimy substance. When fired at an unruly mob it causes rioters to simply slip over.

Riot police or troops would wear a back pack with three cylinders – one containing compressed air, another filled with plain water and a third containing a supply of very dry, finely ground, polyacrylamide powder. A nozzle, resembling a shower head, would blasts two separate jets, containing the water and the polymer powder, in the general direction of an ugly crowd.

As the two jets mix in the air, after clearing the nozzle, they create a slimy mixture that covers the ground and causes everyone in the area to fall down. Even vehicles should be unable to get a grip on the goo, the patent says. And because the gel is non-toxic, it should cause no permanent harm, besides a few bruised bottoms, that is.
