A water barometer or storm glass is used to predict stormy weather. It works because of changes in atmospheric pressure. The top of the spout is above the water level and open. When air pressure sinks lower than when the body was sealed with water, the water level in the spout rises above the level in the body.

How do I get my storm glass to work?

Answer: To reset the storm glass you want to slowly heat the tube while at the same time tilting it back and forth to mix the crystals back into the liquid. You only need to slightly warm the tube, not get it hot. You are only heating the tube and the liquid so that it is slightly above room temperature.

How long does it take for a storm glass to work?

It needs about 15 minutes to gradually heat and tilt the storm glass so that the crystals dissolve entirely. You should end up with a tank of a fully transparent liquid with no crystals or sand in the centre.

The glass on this barometer seems sturdier than the glass on my parents barometer, and the chrome wall mount is bright and shiny while theirs was just black wrought iron.
