the.com/caster
The wheel that lets furniture flee the scene of its own crime.
means A small swiveling wheel fixed to the bottom of furniture or equipment so it can be rolled rather than lifted.
from From 'cast,' in the old sense of 'to throw or set in a direction' — a caster is literally the thing that casts, or throws, the object's motion this way and that. The word split off from the shaker-of-salt 'caster' (same root, different job) sometime as furniture-makers needed a name for these little rolling feet; both senses trace back to Old Norse 'kasta,' to throw.
