THE STRANGE CASE OF THE FLYING CUSHIONS

Usually people use the cushions to make a chair more comfortable... Well don't ask me why but in 4th B there aren't used for that precisely.
It happened in a class change when some cushions started to fly magically and jump out the window (yes it's a rather strange hobby but they can only do the cushions of 4ºB...) and the tutor couldn't believe what he was seeing: His students were champions of the world in launch of cushions!!!!
