Invisible Lift
A silent, unseen vertical transport mechanism that descends and ascends a tunnel's depth without visible cables or guiding rails. It moves by exploiting zero-gravity physics through a disguised cylindrical metal column embedded in the tunnel wall, appearing as structural support when inactive. Travelers experience its motion primarily through weightless sensations rather than visual perception — the Doctor studies its operation while using a loaf of fruit as misdirection, while companions like Leela and Idas brace against its abrupt changes in acceleration. The mechanism serves to transport individuals vertically through restricted tunnel systems without exposing movement to surveillance or detection.
