When you want to keep track of real short breaks, here's a way to do it! This gravity hourglass is sand-filled and suspended in a liquid-filled glass cylinder. It measures three minutes of time in any color you choose!

An awesome desk-topper, It's a perfect client gift as well! When the cylinder is flipped, the sand within the hourglass moves down while the hourglass itself floats up.
