This floating sand timer helps you keep time in a unique way. Composed of aluminum, the timer's frame features two round end caps and three pillars. The central tube contains water as well as an internal bulb filled with sand. When you flip the timer over, the internal bulb begins to rise in the tube, even as the sand slowly trickles down. Add the timer to a desk or shelf for quick access and use it throughout the day.Details:Silver colored3" x 3" x 8"MetalFor indoor use only
