The Storm Glass Barometer came into general use during the early 1700s. Sailors attached this instrument to the mast of their ship and by interpretation of the constantly changing crystal formations within, relied upon it to forecast the weather for nearly 250 years.
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. When you now turn the bottles upside-down, the water starts gurgling down, creating a large vortex (you might have to squeeze the lower bottle a bit to start the process)
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.
Incredible: a key ring that turns into a proper kite of nearly half a metre wingspan! It doesn’t need any rods, it is stabilised by two air pockets. The whole kite fits into a tiny pocket that is attached to a key ring. A fantastic toy for young and old. Complete with 15 metre string on a spindle.

The Crookes Radiometer, also known as a “light mill”, consists of a partly evacuated glass bulb, inside of which a set of vanes is suspended on a vertical axle. One side of the vanes is black, the other silver coloured. When exposed to bright light, the vanes start rotating about the axle.
The Goethe Barometer consists of a partly filled glass sphere with stand that has a spout attached to its bottom. The spout is open at the top, which allows the atmospheric pressure to change the level of the liquid inside.
The principle of this thermometer was discovered by Galileo Galilei: Suspended in the liquid inside the cylinder are a number of weights which are attached to sealed glass bulbs.
