An ordinary Pocket Handkerchief is freely displayed. It is folded and placed on the table and magically becomes animated, as if a ghost were trapped under it. The handkerchief jumps up and down, in an uncanny manner. Then the ghost vanishes, and the handkerchief is opened to show there is nothing in it – its just an ordinary handkerchief.
Wrap a small slate and piece of chalk under the hanky, and the “spirits” write a message on the slate.
Special Handkerchief, and illustrated instructions supplied.
