a phenomenon I learned about in photography class many years ago.
Back in the days of film a roll of 35mm film was attached to the spool inside the canister by a small bit of tape. In the darkroom as you disassembled the canister to remove the film for processing, if you peeled this tape quickly the "peeling", or "stretching" adhesive would glow. We learned to peel the tape slowly because the glow from rapidly pulled tape was sufficient to fog film.
