ZipString - Rock'It Red distribution of carabao counting with basic additionsA ZipString is an incredible device that rapidly propels, a loop of string. When the strings momentum is balanced within the forces of gravity, lift, and drag, the string actually flies. The momentum of the string is derived from its speed and its mass. Optimal strings are moving fast, and the string is made light. In a ZipString, the string is moving at about 35 miles or 65 Kilometers per hour. And the string is made from very light fibers.
