Hand-Blown Magnetic Hourglass

This unique hourglass puts a scientific spin on the sands of time. A magnet in the wood base interacts with the ferrous sand to produce mesmerizing, temporary stalagmites in the lower chamber of the glass.

The natural timer magnetically marks one minute and makes a great gift for gadget-loving co-workers, parents, teachers, or your own desktop.
