Zip String Fidget - Light Green

Prepare to amaze your friends as they watch a loop of string seemingly defy gravity, floating and dancing in the air before their eyes!

This extraordinary fidget toy propels a loop of string at rapid speeds, creating a mesmerizing visual effect. The magic happens when the string's movement strikes the perfect balance between gravity, lift, and drag—causing the string to fly. The string, made from lightweight fibers, zooms through the air at an incredible 35 miles per hour.

The secret to the string’s flight lies in its textured surface. Instead of being smooth, the string has tiny filaments that fan outward, creating drag as they move through the air. You can even feel the airflow when you place your hand near it! As the string loops through the air, tension pulls it back toward the device, but its speed and the drag from the filaments generate lift, especially at the farthest end. When the lift exceeds the string's weight, the string takes flight—hovering and spinning in perfect balance.

This gravity-defying fidget toy doesn’t need batteries—simply recharge it with the included USB-C cable, and you're ready to go!
