So maybe initial tests of Sticky Foam as a less than lethal anti-personel tactic fell flat, the U.S. military is exploring further uses of the stuff as a deterrent against vehicles. However, this stuff has always had promise against the living dead. Zombies aren’t so fleet of feet, so a good dose of the sticky stuff would halt their progress rather effectively. The only thing really holding it back as a great anti-shambling-personel device was the lackluster initial results against real living (and agile) people. Now that the government is looking for alternative uses, there will be a potential for any slick survivalist worth their salt to get their hands on a Sticky Foam delivery system to put up some decent barriers preventing the needless showering of zed entrails and fluids in self defense situation. Less than lethal Z-Defense if you will.
