Magnetic Hourglass from ThinkGeek
http://www.thinkgeek.com/jjrn?cpg=yt
- A ThinkGeek exclusive
- Mesmerizing - we should warn you that you may find yourself watching it for hours
- Filings take roughly 30 seconds to fall
(This is not a precision timekeeping device, although we do sell those, also)
- It's also fun to move the hourglass around the base
- Reminds us of a soot sprite
- Materials: Glass hourglass, iron filings, and a rare earth magnet in the metal base
- Dimensions: 6 3/4" tall x 3" diameter base
- Weight: 7 oz.
- Includes hourglass and base
- Note: Be especially careful when setting the hourglass on the base when the iron filings are already all in the bottom section. It may be a weak force, but magnetism can be pretty strong!
