Thunder glass barometer Esschert

The effect of this weather forecasting thunder glass or weather glass has been known since the beginning of the 17th century. At high air pressure (good weather) the liquid level in the nozzle of the thunder glass is pressed down and at low air pressure (bad weather) the level in the nozzle of the thunder glass rises. In the event of a thunderstorm, the liquid will be able to rise so far that it drips from the spout of the thunder glass. Fill the thunder glass (only a third) with either boiled or demineralized water and color it with the supplied (blue) ink powder.

This thunder glass comes in a printed gift box and with a syringe for easy filling. Blue ink powder is also included.
