A bullwhip consists of a handle section, a thong, a fall, and a cracker. The main portion of the whip's length is made up of a braided body or thong. Made of many strips of leather, the number of braids or plaits is an important factor in the construction of the whip. The handle is usually short, being between 8 and 12 inches long which is held in the palm of the hand when cracking. Tied to the end of the flexible fall, is an even more flexible piece of string or nylon cord or wire called the cracker or the popper. The cracker functions to disperse sound so it can be heard more easily.
