Watching time pass you by doesn't have to be a monotonous task. Whilst your normal hour glass lets the grains of sand flow and rest at the bottom, your Magnetic Sand Timer creates quite a different picture and can create a really neat desk toy for visitors to marvel at. With the Magnetic Sand Timer, the filings are magnetised by the base and come together to form uniquely chaotic shapes as they fall through the timer with each turn of the glass! Without the base, your Sand Timer will work just like a normal hourglass, but put it on the magnetic base to create a different magnetic structures each time! Times for 30 seconds.Dimensions: 13cm tall x 8cm wide (including base).
