  • silk shirt vest for knifes
  • hemp makes really strong armor aswell, the first hempcars were said to be bulletproof hemp would probably work great for bulletproof facemasks and helmets too.

rail guns

A friend and I had built a working railgun out of an old disposable camera , aluminum tube, some copper wire and a steel nail. the concept is it pulls the nail to the center of the aluminum pipe with copper wrapped around. then by the time it hits the center the flash has gone off and it continues to fly ,otherwise it would pull it backwards after passing through the center.

a 8 stage railgun with optical sensors would be very cool to try.

  • All plastic 3D printed stealth gun from “in the line of fire”
  • you can 3d print the lower receiver for ar15 and clip. just need to order the barrels which is legal without registering them.
