Ray Bradbury’s Fahrenheit 451 tells the story of a dystopian future where books have been outlawed and are destroyed by firemen who set them ablaze. But in an ironic twist, Super Terrain, a publisher in France, has created a new edition of Bradbury’s classic that actually requires extreme heat in order to be read.

Jo Frenken shared this video to Instagram showing a prototype copy of the book, which was developed by the Charles Nypels Lab at the Netherlands-based Jan van Eyck Academie—a research institute known for its experiments in materials and media. The pages of the book appear completely blacked-out—like a redacted CIA file—as you flip through them. But when heat is applied, using a flame from a lighter, in this case, the heat-activated ink disappears and the underlying text is revealed.

Super Terrain will apparently be making this unique version of Fahrenheit 451 available sometime in 2018, but we recommend maybe grabbing a hair dryer to read it. An actual open flame is probably a bit too risky.
