What you get: Magnetic Sand Hourglass. A two piece set, featuring a hand blown hourglass and metal magnetic base and one rare earth magnet. Note: actual time kept varies between timers, but is approximately 30 secs.
WARNING: CHOKING HAZARD Small Parts. Not for children under 3 years.

This kit comes with the freestanding hourglass, and the glass seems pretty strong, as I didn’t break it and comes with a metal stand and one rare earth magnet. So you pretty much have everything you need.

What’s great about this hourglass timer, it doesn’t use boring old sand but fine magnetic filings.

Turn it over, and as the magnetic filings succumb to gravity and stack up on a magnet in the base, they produce artistic patterns and structures. A new one every time.

It’s like memorizing as you'll be intrigued by how the ferrous material interacts with the magnetic field.

I bought mine at Cost plus, but you can buy it online here
