Pepper Spray Gun

Start up company Salt has developed a gun they say doesn't need to take a life to protect. The gun shoots pepper spray bullets that explode when they hit a solid object, not even needing to hit their target to be effective. The powder mixture causes temporary blindness, makes the lungs constrict and stings the human skin. http://www.engadget.com/2015/10/29/salt-gun-pepper-spray/ #tech
