My Daughter Gave Me a Fitzroy Storm Glass for Christmas

I copied this GIF from the web. It's been sped up. 

The actual speed is much slower, too slow to detect.

My Fitzroy Storm Glass is beautiful.  It's perfect for the desktop, sitting by my Sterling Engine.

From Wikipedia:
FitzRoy was a pioneering meteorologist who made accurate daily weather predictions... He achieved lasting fame as the captain of HMS Beagle during Charles Darwin's famous voyage.

Internal and external troubles at the Meteorological Office, financial concerns as well as failing health, and his struggle with depression took their toll.

On 30 April 1865, Vice-Admiral FitzRoy died by suicide by cutting his throat with a razor. FitzRoy died having exhausted his entire fortune on public expenditure.

How he said the storm glass works:
"if fixed, undisturbed, in free air, not exposed to radiation, fire, or sun, but in the ordinary light of a well-ventilated room or outer air, the chemical mixture in a so-called storm-glass varies in character with the direction of the wind, not its force, specially (though it may so vary in appearance only) from another cause, electrical tension."

It's great to watch the crystals form and change.
