In a traditional hourglass, falling grains of sand just make a big pile of sand, but the falling iron filings and embedded magnet in the metal base of this cool new Magnetic Hourglass make a fascinating and ever-changing pile of artistic patterns. The fun doesn't quite last an hour in this hourglass, but when flipped it does alleviate boredom at the office for 60 seconds or make an interesting minute timer for other activities. It's also available in 2,3, and 5 minute timers and in various colors. Check out this VIDEO to see it in action.
