Newton's Gravity Glass is a sand-filled hourglass suspended in a liquid-filled glass cylinder. When the cylinder is flipped, the sand within the hourglass moves down and the hourglass itself floats up. The hourglass inside the cylinder measures 3 minutes of time with either blue, magenta, or purple color sand. Makes a great corporate gift and very popular with children!
