2 hunks of string and some rocks, or small bags full of dirt, sand or gravel and you've got a bola. Much, much better chances of success. Practice with it first. The short string is tied to the middle of a string 2x as long as the short one. You hold onto the weight that is tied to the short string, and spin the bola around your head, and then "cast" it at your target. In flight, the 2 other wts make the string "spread open", preparing the bola encounter and entangle anything that it touches.. Practice "wrapping up" a stake in your yard.
