Slingshots may seem outdated in the world of video game and TV entertainment, but outdoorsy types will enjoy using them for target practice. The primitive tools also come in handy when re-enacting the story of David and Goliath. You can make a slingshot for a child with a few common hardware tools and a sturdy rubber band. When giving a slingshot to a child, make sure he understands not to aim the weapon at people or animals.
Look for a single branch that separates into two branches in a Y-shape. The main branch should be about 3/4 inch in diameter to fit comfortably in a child's hand.
Saw off the single branch about 3 1/2 inches below the two split branches. Saw the other two branches to a length of 3 ½ inches each.
Cut off all bark with your knife to promote drying and make the slingshot more comfortable to hold.
Place the slingshot in a cool, dry place so it can dry out evenly. Wait for the wood to dry thoroughly before proceeding.
Sand the slingshot to smooth out rough edges that could scrape the child's skin.
Wrap string around the slingshot handle's grip and attach both ends with tape. Wrap duct tape over the string to make the grip soft and comfortable to hold.
Snip through a thick, large rubber band to make it a single strip.
Place the ends of the strip against the top of each slingshot prong and attach them with small rubber bands. Stretch the larger rubber band back several times to ensure a secure fit. If the band slips, use more small rubber bands for added security.
Wrap duct tape around the part of the rubber band that you pull back. This will add strength to the band.
Place a piece of ammo against the duct tape on the rubber band and pull the rubber band back while aiming at your target. Release the rubber band to fire the ammo.
