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

Measures 3 minutes of time with either blue, yellow, or purple color liquid. A perfect corporate gift!

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

6" tall

Hourglass inside the cylinder is a 3 minute timer
