Magnetic Sand Hourglass

The Magnetic Sand Hourglass is a fun desktop diversion.

Flip it over and watch the grains of iron stack up in seemingly impossible formations thanks to a magnet embedded in the wooden base.

The craggy configurations of the iron filings eventually build into an ordered hemisphere with a spiky surface. Like your favorite movie, you can enjoy watching the Magnetic Sand Hourglass over and over again.

Timer is approximately 35 seconds long.
