Add a touch of interesting science to your desk or lab with this MagnaGlass hourglass! Filled with ferromagnetic iron filings, a magnetic field turns each particle of sand into a tiny bar magnet, so that they stick together creating amazing patterns and structures. The base contains a magnet, so when you turn over the hourglass, the fillings fall down onto the magnetic field.
The hour glass became widely used in the 14th century on boats as well as in churches and homes as time keeping devices, they are now more of a decorative item. The Magnaglass Hourglass runs for 1 minute before it needs to be flipped again, creating unique structures every time.
Suitable for ages 10+
