I've always been fascinated by the flow of sand thru an hourglass. This hourglass raises the bar.

Instead of sand, it contains iron filings. In the base is a magnet. As the 'sand' flows, the magnetic field causes it to stack in different shapes. When weight and gravity builds up, the shape collapses into a more compact shape. New grains then build on that base. Fascinating. 

I purchased my hourglass thru Amazon. When in Amazon, search for "Magnetic Hourglass". There will be several alternatives. This one is "Zicome Hand-blown Glass Sand Timer Magnet Magnetic Hourglass with a Iron Base" There are others now that I did not see previously.

Yet, as a woodturner, I want it to show some wood. However, in this case, the wood is only a simple base.

The base is an example of urban forrestry. A friend's neighbor cut it down and I was fortunate to get several pieces. Some was not large enough for a bowl. This I turned into a straight cylinder, coated it was green wood sealer, and left it to dry in my shop. It has now been just over 2 years, the wood is dry and can be used for spindle projects like this one. It is finished with Mylands friction polish.

Good turning.
