Liquid Timer Yellow - White Sand
This beautiful hand-blown glass sand timer features double action powered by gravity. When you flip the Newton's Gravity Glass over, the hourglass within the liquid-filled glass cylinder gradually moves upward as the sand within it falls. The sand takes approximately 3 minutes to fall to the bottom of the hourglass. This is an awesome desk accessory will make you wonder how it does that double gravity thing!
