A small tube that has a great effect: Take two ordinary plastic drink bottles, fill one two thirds with water and then connect the two bottles with our Bottle Tornado tube.

Our Goethe Wall Barometer is hand blown from a traditional glass formula called “forest glass” in Lauscha, Thuringia in Germany. It is a copy of the original barometer from 1792/93 that was found in Goethe’s house in Weimar after his death. The slight green tinge of the glass and its texture make it look like a real antique.
