The Magic Screw is a desk toy consisting of a spiral shaft that rotates inside a two-column structure, mounted on a circular base. By turning the lower part, the central spiral rotates and moves up or down along its axis, offering a fluid and continuous movement to observe and handle. The exposed structure lets the eye flow along the entire mechanism, making it a decorative object as well as a pastime for the hands. It occupies a base of 12 cm by 12 cm and a height of 18.8 cm
