Bow and Arrow. You will need to gather materials such as wood for the bow, string for the bow, and a straight, thin shaft for the arrow. You can use a variety of materials for the bowstring, including natural fibers like hemp or sinew, or man-made materials like nylon or Dacron. To create the bow, you will need to bend the wood into the desired shape and attach the string. To create the arrow, you will need to straighten and sharpen the shaft and attach feathers or other materials to the back end to act as fletching and stabilize the arrow in flight.
Spear. You will need a long, straight shaft and a sharp tip. The shaft can be made from a branch or sapling, and the tip can be created by attaching a sharp rock or bone to the end of the shaft using natural adhesives like plant sap or animal hide glue.
Blowgun. You will need a long, narrow tube and small projectiles called darts. The tube can be made from a hollow reed or bamboo, and the darts can be made from thin sticks with sharpened tips. You can use natural adhesives to attach feathers or other materials to the back end of the darts to stabilize them in flight.
