You will need: a black cup, Halloween stamps, craft stick, white paint and a ghost shape cut out of construction paper.
Directions: Have kids us Halloween stamps and white paint to print onto the black cup. Have the ghost shape cut out or if kids are old enough they can cut the shape themselves. Attach the shape to the craft stick. The child can give his ghost a face. An adult cuts a hole in the bottom of the cup the same size as the craft stick.
When the cup is dry, the child can pull the craft stick down to make their ghost disappear or push it up to make it appear.
