1980s Self Defense Tool That No Longer Exists

Back in the 1980s, a unique self-defense spray called Dye Witness became notorious for more than just stopping attackers 😳 Unlike ordinary pepper spray, it blasted out a thick dark green foam packed with a special marking dye designed to stick to skin and clothing for days — making suspects incredibly easy for police to identify later. The bizarre-looking foam and nearly impossible-to-remove stain made it one of the most memorable personal defense products of its era.
