How do I make a sling shot?
user
There are several different types of slingshots, but the basics are the same.  You can find instructions online, in Wikipedia’s entry on the slingshot, or maybe by looking for a particular style of slingshot, like a “Pen Maze”, “Square Duct”, “Medieval Dart”, or “Hook” style.  
But if you have a basic understanding of mechanics, you can make a slingshot using materials at hand.  If you wanted to, you could make a slingshot out of a golf club, for example.
