d Donderglas – weather forecaster with a story ⛈️🌤️
With this classic thunder glass you bring a piece of historical science into your home. This elegant instrument has been used to predict weather changes since the 17th century – and it still does!
The principle is simple but fascinating: At high air pressure (good weather) the water level in the spout drops, while at low air pressure (storm approaching) it rises. Sudden drops in pressure can even cause water to drip from the spout – a clear sign that a storm is approaching.
Dimensions: 28 x 13.5 x 12 cm (HxWxD)
Material: Glass with an elegant wrought iron frame
Includes: Syringe for easy filling and blue food coloring to color the water
Both decorative and educational – a wonderful gift for lovers of weather, science or antique-looking home accessories.
