If you’ve seen our Admiral Fiztroy Storm Glass, you probably have asked yourself, how does it do that!?
Admiral Fitzroy designed the storm glass in 1750 and we still don’t know exactly how it works, but there are a few theories.
One theory is that temperature and pressure affect solubility and how the clear liquid will then cause precipitants to form. Although this idea makes sense for most of us because heating a liquid allows things to be dissolved easier. Think about cooking. You heat a pot of water in order to dissolve a cup of sugar. But this theory doesn’t exactly work for the Fitzroy storm glass because others have reported that they have observed several different formations in the glass tube at the same temperature.
Some people have also thought that the surface interactions between the glass wall of the storm glass and the liquid inside create the crystals. This can be related to the effects of electricity or the phenomenon of quantum tunneling. Quantum tunneling is when a particle tunnels through a barrier it normally wound not cross through for example something passing through the glass wall of the storm glass and into the liquid forming crystals.
However the storm glass works, it is an ingenious piece of ingenuity and definitely a conversation piece that will have everyone guessing on how it works.
How to Predict the Weather using the Admiral Fitzroy Storm Glass:
- If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter
- If there are threads near the top, it will be warm or windy
- If the liquid contains small stars on a sunny winter day, then snow is coming
- If there are crystals at the bottom, this indicates frost
- A cloudy glass with small stars indicates thunderstorms
- If the liquid is clear, the weather will be bright and clear
