14.2   Spear Gun

             It resembles a long hand gun where a barbed iron bar is shot into a fish, lobster or octopus by means of stretched rubber as the source of power. The spear is made of wood, about 1-2.8 m. long. The end of the iron bar is fastened in the trigger of the gun, simultaneously stretching the rubber band. The trigger is pressed and the iron bar is released, thus hitting the target. A canal is carved in the middle of the wooden gun while the iron bar is guided by a circular metal ring.
