Whatsabox—A simple box of cardboard turns out to be far from simple. First it has an open top and closed bottom, then two tops, then two bottoms-and a ball placed into the box finds itself trapped inside, then just as mysteriously is released.
This is the manuscript that describes this amazing routine and prop construction in great detail. Seven clearly illustrated pages.
Self published by Robert E. Neale, this deserves a second look!
