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.
Extremely high demand - expect 3 or more weeks for it to arrive. Limit 3 per person.
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.
