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 iron base.
The craggy configurations of the iron filings eventually build into an ordered hemisphere with a spiky surface. You can enjoy watching the Magnetic Sand Hourglass over and over again. Great for home decorations. A good gift for your families or friends
