Fort Bourtange is a star fort located in the village of Bourtange, Groningen, Netherlands. It was built in 1593 under the orders of William the Silent. Its original purpose was to control the only road between Germany and the city of Groningen, which was controlled by the Spaniards during the time of the Eighty Years' War.

Sleep under the Stars, hosted by Hepburn Wind, has given us an opportunity to enrich our daily life with art. Thanks to this festival, a regular wind turbine was turned into a marvelous peace of art. The artwork is especially noticeable, since its theme greatly contrasts with the background behind the wind turbine. Moreover, the idea of drawing a woman-giantess walking over the mountain tops on a large conical object is quite extraordinary. Nevertheless, the grey and green colors of the picture were very well chosen for this particular image. You can only imagine the obstacles that the artists had to face when making a picture on such a large object. However, nowadays, people never cease to amaze with their ingenuity, leaving us gaping in awe at their creations.

If we were to burn NH4Cr2O7 with HgSCN in the Dark Ages in Europe and show it to anyone, it is us who would be burning next on a fiery cross of Inquisition. And it’s no wonder, since this experiment produces a truly marvelous result. At first, as you ignite the mixture of NH4Cr2O7 and HgSCN, all you can see is that it is slowly burning with a reddish flame. After a while, however, a crater is formed in the middle of the burning pile, and then, suddenly, tentacle-like appendages start sprouting from the burning mixture. And you can almost hear the scream of the mad occultist – “Come forth, Kraken! Come forth!” But of course, this is simply a chemical reaction that is called the "Pharoah's Serpent". It was also often sold in firework stores until people realized that it was toxic.
