Make a silly, scary mask using paper plates and cardboard egg cartons. Cut eye holes in a large paper plate. Cut apart the cups of an egg carton and arrange them on the plate to make a nose, beard, bumps. When you have an arrangement you like, use glue or masking tape to attach the cups in place. Paint the mask with finger paints and add facial features. Let the paint dry. Punch a hole in each side of the paper plate and string a piece of elastic or string through each hole to go around the head.
