i heard a prisoner built a zip gun using paper mache, a few bits plastic (i think some pvc pipe), and a combination of chemicals he stole from the kitchen (the chemicals were used for cleaning, and a marble. so he used paper mache and pipe or something like that to make the barrel, he placed the chemicals in the improvised gun and then dropped in a marble. he positioned the chemical filled end of the tube against a heater, and i suppose the heat caused a chemical reaction thus firing the marble at high velocity. of course that process would be ineffective for killing, but he never intended to fight with the gun, because he used to commit suicide. i heard this story from a friend who claims to have heard the story from a reliable resource, i can't confirm if it was a true story, and i dont know if it is possible to construct an improvised gun like that. either way it's amazing how prisoners come up with wacky ideas on how to construct weapons. |
