Iron filings may not seem to be very much fun, but someone clever once noticed that they form cool shapes when they come into contact with a magnetic field. Combine crazy magnetic iron filings with an hourglass and BAM...MagnaGlass! An endlessly fascinating executive stress relief toy!
The Science of Iron Filings and Magnetic Fields
Iron filings are small, lightweight pieces of iron that can be used to visually represent the field lines in a magnetic field. You may remember school science experiments that used the filings to test a magnet or kid's toys that use a magnet with iron filings to make funny shapes. Each tiny iron filing becomes magnetized as they enter a magnetic field and they will align with their neighbours to make chains.
Flip the MagnaGlass to make the iron filings fall towards the magnetic base. At first they will fall freely, but as they come into contact with the invisible magnetic field produced by the strong magnet in the base, they will line up to make crazy, spiky shapes. Flip the glass back over and the process repeats. We warn you: it's pretty riveting and is a great way to relax and de-stress!
The MagnaGlass is a wonderful interactive desk accessory and it will make an interesting gift for anyone who works in an office or owns a desk. We suggest it as a refreshingly different gift for your boss or work colleague at Christmas or for a fun birthday present.
