Make a Semi-Auto K’NEX gun


Don’t let yourself be caught without a weapon when the zombies invade.

Stretch each rubber band from the tip of the barrel to the white pin, only put one rubber band on each white pin. after loaded (doesn’t have to be fully loaded, you dont have to put on all 8 rubber bands each time you fire) pull the trigger, theres 8 trigger so you have to move your finger up every shot. – Link
