Table Top Weather Glass Barometer for sale. Buy from The Science Company.

This handblown weather glass barometer is suspended from a brass arch over a brass spill cup. The wooden base and arch support are rosewood, polished to a soft, beautiful glow.

The water barometer has served as a simple forecaster since the time of whaling ships to the present. Consult the Weather Glass each day for impending weather changes approximately 8 to 12 hours ahead.

Low barometric pressure allows the water level in the glass barometer spout to rise, indicating stormy weather ahead. High pressure causes the water level in the spout to drop, predicting fair weather to prevail.

Just add water per instructions, plus drops of food coloring for heightened visibility.
