Newton Gravity Timer - 3 Minute Pink  10 inch

The Galileo Shop

Newton Gravity Timer

$ 19.99

Newton's Gravity Glass is a sand-filled hourglass suspended in a liquid-filled glass cylinder.

The Gravity glass is an awesome desk-topper and a question-generating educational tool. When the cylinder is flipped, the sand within the hourglass moves down while the hourglass itself floats up.
