Buy cheap tennis balls from a discount shop and make these hysterical tennis ball puppet heads.
Using a sharp knife, scissors or Stanley knife (adult should do this) cut a horizontal cut half way across the tennis ball.
Glue on google eyes.
Make hair using wool (or permanent marker).
a) Cut lengths of wool. Just make this approximate because you can trim the hair
b) Tie a knot in the middle
c) Trim the hair to desired length.
d) Glue the wool on top of the head.
Add lips with a permanent marker (and eyelashes too!).
Allow to dry.
Do a puppet show! Just press on the sides of the ball to open the mouth. Hysterical!
