The effect of barometers to measure weather forecasts has been known for around 400 years. One of the first models is this so-called thunder-glass. It works very easily. With high pressure, but also in sunny weather, the water level is pushed down into the spout. At low pressure, such as with clouds and rain, the water level in the spout rises. In an approaching storm, the water level rises so strongly that it can overflow. With decorative cast iron wall holder.
