Michael Fröhlich's Jowett Javelin rotting car in his forest sculpture park in Neandertal Germany, September 11, 2016. An eccentric artist has collected fifty vintage cars and left them to rot in a forest – and now they're worth over $1 million.

Oh, those daredevils! They’re always willing to pull off another incredible stunt to gain fame and glory. Sometimes it’s something incredibly stupid, but sometimes it is simply incredible. The stunt that you can see on this video is of the latter kind. Who would have thought of attaching a jet engine to a bicycle? And who would have dared riding one? Circuit Paul Ricard, that’s who. On November 7 2014 he reached a whooping speed of 333 hm/h (207 mph) on his bicycle. Now that is a tale to tell your grandchildren… if you ever live long enough to see them with a lifestyle such as this.

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.
