Magnetic Sandtimer
This unique hourglass timer swaps boring old sand for 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. The hourglass itself is freestanding, and can be used on its own as a traditional sand timer as well as on the magnetic base. The rare-earth magnet contained in the base is powerful, and you'll be intrigued by how the ferrous material interacts with the magnetic field.
