Vapor-Phase Doorknob

This doorknob converts solid matter into breathable vapor upon turning, allowing users to subtly shift physical boundaries between rooms while remaining inconspicuous. Upon installation, homes require specialized atmospheric recalibration systems to accommodate the nebulous interface. Upon activation, occupants must briefly hold their breath before exiting through re-solidified doorways; however, this minor inconvenience ensures seamless transitions throughout dwellings. Breathable architecture becomes accessible via easy-to-use controls on accompanying smartphone app VaporFlow Pro.
