Appearing to be straight from the wall of a French medieval castle, this 17.5 inch high water barometer, also called a "Thunder Glass", has served as a simple weather forecaster since the Middle Ages. Now you can consult this Weather Glass Barometer daily for impending weather changes approx 8 to 12 hours ahead.
Low barometric pressure allows the water level in the weather glass 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.
