Decoy Detonators are black horn-like magical objects designed to create a diversion. After being dropped, the decoy runs a fair distance away, makes a noise like a loud bang, and releases clouds of black smoke, diverting attention from the user.


Invented by Fred and George Weasley, they were for sale at Weasleys' Wizard Wheezes. Fred and George gave several of these devices to Harry Potter, refusing payment on the grounds that his thousand galleon investment had allowed them to start the business.[1]

Harry used one on 2 September, 1997, during the Infiltration of the Ministry of Magic, to create a diversion to distract several Ministry of Magic employees. He subsequently entered Dolores Umbridge's office to search for Salazar Slytherin's Locket, one of Lord Voldemort's Horcruxes.[2] Decoy Detonators were among the various magical items that became trapped as Foundables across the Wizarding world in the Calamity, which happened during the 2010s.[3]
