Colorado-based artist Stefanie Hook made a Marauder’s Map mask that changes colors when you breathe into it.
When it reaches a temperature of 82°F (27.778°C), the mask reveals a detailed image of the Marauder’s Map.
Hook owns and operates a company called Colorado Pony Express (CPEX), through which she sells hand-sewn plush toys and accessories. She’s also started to sell face coverings in recent weeks. The masks are not medical-grade, according to her website, but were created using the Centers for Disease Control’s (CDC) sewing instructions.
