Furchalka

This is a modern twist on the classic childhood toy made from a button and string. Instead of a button, it features a custom 3D-printed spinner threaded onto a closed loop of string. Here's how it works: pull both ends of the string apart, and the spinner springs to life, spinning rapidly while producing that satisfying, rhythmic whirring sound. The harder you pull, the faster it spins and the louder it buzzes.
