11. A Game of Thrones’ Wildfire Was Real
Anyone who has watched George R. R. Martin’s Game of Thrones, or read the book, is no doubt familiar with the Wildfire. Able to burn on, even underwater, it was used significantly to protect King’s Landing from naval attack. Terrifying, this is no fantasy. The Byzantines had a substance known as Greek Fire that could burn under water. It is still unknown what the compound consisted of, as it was a state secret that creators took to their graves.
