Variations in barometric pressure are associated with weather systems and these changes are immediately revealed by the water level in the spout. A low level of liquid in the spout indicates high-pressure and fair weather can be expected. A high water level is associated with bad weather. In cases of severe weather and major storms the water may even run out of the spout. Wooden base included. A fun and functional accessory.
