Laboratory Sink
The towering porcelain basin in the laboratory, featuring a metal plughole that Smithers plugs during a distracted argument, trapping the shrunken Doctor, Susan, Ian, and Barbara below. The sink's slick sides are climbed by Susan and the Doctor to exploit echoes for calling companions, while Ian and Barbara perch at its rim, eyeing a dangling chain for descent. The plughole's sealing blocks the protagonists' only escape from giant-scale perils, including chemical residue and insect threats.
