This drop announces the weather to you. The beautiful home accessory impresses with the contrast of rustic wood and clear glass. The great thing about it is the effect: White crystals predict the weather. Here’s how it works: The stylish glass drop is filled with camphor salt solution. The salt crystals inside react to electromagnetic waves as well as changes in air pressure and temperature. Weather forecasts of up to 12 hours are possible, depending on the placement. If the crystals are visible, humid and foggy weather is to be expected, while a cloudy glass indicates a storm is likely. Conversely, if the glass is clear, you can look forward to fair weather conditions. Even Charles Darwin relied on such a storm glass during his travels. Filled with camphor salt solution. It is recommended to place it near a window. The glass takes about 2 weeks after shipping to provide reliable forecasts.
