Do you have a secret you don’t want anyone to know? How practical would it be with the Marauder’s Map from Harry Potter if you could see anyone nearby and quickly hide under the invisibility cloak as soon as they came too close. The magic words are displayed on this Harry Potter mug and when you fill it with a hot drink the print on the mug changes.
