Could be worse. Teacher takes a larger box, takes out what looks like a black book. Presses a button, a lift comes up, the book is placed inside and teacher then uses all her strength to push the lift back down. Then there are lots of bashing, crashing and clunking noises and a film starts playing, carefully obliterated in parts by a strange black and white line that moves down the screen on occasions. Sometimes the film stops and teacher removes the book which proceeds to leave its entrails inside the machine and across the table. Teacher then opens an actual book and curses silently.
can't be right, they'd have had to put up a curtain around it before beginning the work...
