Storm/thunder glass with wooden base and brass drip tray, also showing the weather forecast.
A storm glass is a very effective weather forecaster, superb with thunder; incredibly, it is always accurate.
The water rises in the spout at a low air pressure and drops at a high air pressure.
With an upcoming storm, the glass can even overflow.
For that reason, it has a brass drip tray beneath the glass
The device works best in a uniformly heated room. Don’t hang it in direct sunlight or above a heater.
Top up the glass with water, preferably distilled (pharmacist) or demineralised to approx. 2 cm above the beginning of the spout.
Possibly colour with a few drop of dye (green, blue, red, purple will fit in any interior)
Because the water evaporates gradually, you will occasionally need to refill the glass.
In original box
