The Newton 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.

The hourglass inside the cylinder measures 2 minutes of time with either blue, magenta, or purple color sand. A perfect corporate gift!
