The Muggle-Deterring Gate was a magical invention advertised by the Rumours! magazine. Whenever a Muggle would touch the gate, it would emit a Muggle-repelling alarm of the user's choice. The choices included a ghostly wail of woe, a sinister cackle of laughter, or an eerie scream of pain. The product was not approved by Ministry of Magic.[1]
