So, it's supposed to be a word for a scientific mistake.
Basically they've tried to make something, but it didn't turn out right, so they put it in storage and they labelled the room
"______ Storage"

Something along the lines of faulty/flawed/erroneous/defective?

The Nope Room.

Defect is a good word. Thanks @myujik
