This desktop toy is a classic glass sand timer with a magnetic twist by using iron filaments and a base with a magnet for a mesmerizing effect. 

How does it work?  The glass hourglass is filled with tiny iron filings which are attracted to the magnet in the metal base.  What starts out as craggy configurations eventually turns into a spiky surfaced hemisphere. 

Ages 14+
