The patent pending ZipString carefully balances several forces of gravity, lift, tension, and drag to fly the string in the air. Any movement that a Zipster (a user of a ZipString) does, the string follows.
A 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.
ZipString is mesmerizing right out of the box. With the additional string sizes, your trick mastery will grow.
