a teleportation and transformation device is usually (but not explicitly)

-a device that is defected (in terms of its original function)

-a device that is being used for a purpose other than the one it was originally meant

-a model or a sketch


in this way, a device that is dyysfuntional or useless in its initial ways and becomes functional by being assigned certain (often magical) properties


paradigms: a defected phone booth, a transporter that doesn't move, a shipwrek.

also a pencil, a stone, a book, a tunnel.
