Eavesdropping device; one of Weasleys' Wizard Wheezes (see). An Extendable Ear looks like a piece of flesh-coloured string. One end is inserted into a person's ear, then, on the command "Go," the other end wriggles off to where a conversation is taking place. The Extendable Ear makes the distant conversation easily discernable (OP4)

Artificial eyes in the wizarding world seem to have unusual powers, as a rule.
"Mad-Eye" Moody's artificial eye is round as a coin and electric blue in colour (GF12). It can see through solid objects, including the back of its user's head (GF13, GF14). It can also see through invisibility cloaks (GF19).
