Newton's Gravity Glass

A Newton Gravity Glass is a unique glass sand timer that is encased in a glass cylinder. When you flip over the Newton's Gravity Glass, the hourglass within the liquid-filled glass cylinder moves upward as the sand within it falls. Display this attractive glass timer on your desk or in your lobby. A Newton Gravity Timer makes a great gift! The beautiful hand-blown glass sand timer combines liquid motion elegance with classic sands of time action. Turn it over to engage the hourglass sand timer inside. It will rise as the sands inside of it fall. The sand takes approximately 2 minutes to flow to the bottom of the hourglass.
