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.

Here’s a closer look at the official The Simpsons LEGO set that we previewed earlier here. In celebration of the animated sitcom series’ 25th anniversary, LEGO has paired up with Matt Groening‘s cartoon creation for a two-part collaboration that features arguably two of the largest entities in popular culture. The limited-edition LEGO set depicts the Simpson family’s home, alongside mini-figures of Homer, Marge, Bart, Lisa, Maggie and Ned Flanders. The painstakingly recreated LEGO brick house can be reconfigured and opened up to reveal the inside of the four-bedroom residence. The release of the scaled set will be accompanied by a LEGO-themed episode of The Simpsons, which is set to air on FOX in May. Longtime Simpsons fans can purchase the set for $200 USD at select LEGO stores early next month.
