    In 1910 the German Poet Christian Morgenstern wrote a poem about an inventor and his “Tagnachtlampe”, a lamp that turns day into night when you switch it on. 49 years later, Carl Barks had his Gyro Gearloose invent a similar device, the “gloom light”. Both ideas were never realised, not even filed for patent!

    The five platonic solids are named after the Greek philosopher Plato, who described them extensively in his dialogue “Timaeus”. He saw in them the smallest, invisible building blocks of the world and assigned them to the classical elements. However, the five solids have been known for much longer, as for example 5000 year old engraved stones from Scotland...

    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.

    All our modern cameras have one common ancestor - The Camera Obscura: the light of the outside world falls through a pinhole onto the opposite wall of a room and produces an upside-down picture. In the 16th century the camera obscura was greatly improved by an objective lens, which produced much brighter pictures.

    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.
