Two Way Screw – 7.5cm
AED 15.00
Optical illusion in motion: twist the shaft and watch the right-hand and left-hand nuts travel in opposite directions along dual helix grooves carved into one central bolt. Interlocking threads create a smooth, hypnotic back-and-forth motion that locks your gaze.

The Two Way Screw is 7.5cm of pure mechanical curiosity. A threaded shaft carries two nuts that answer to your touch. Twist the shaft or spin the nuts, and they travel in opposite directions along the dual helix grooves, one riding the right-hand thread while the other follows the left.
Every rotation sets them in motion. One moves forward as the other moves back, and the colors on each piece are yours alone. They keep going until they meet and stop. Reverse the direction and start again.
Pieces like this get picked up without thinking about it. The kind of thing people reach for before they even know what it does. The two nuts meet and stop.
