Rigel and Izzy had fun with this a while ago: a cereal box puppet theatre. They had just as much fun being behind the scenes as they did being the audience. I have since begun setting aside all our empty cereal boxes rather than tossing them in the recycling bin, and have now accumulated--whoa!-- 10 empty boxes! I think it is time to convince the neighborhood playgroup mamas to have a cereal box puppet theatre workshop, and I'll supply the materials. It's great "recycled art."
Cereal Box Puppet Theatre:
empty cereal box
pictures (magazine cutouts of animals, family photos from your printer, etc.)
glue or paste
Cut back of box and sides off so all that is left is the front and the bottom. Glue a popsicle stick on the bottom flap if needed for added support. Cut a window out of front of box. Set aside all the cardboard scraps. Cut curtains out of construction paper, then glue around the window. Cut out the pictures, then glue onto cardboard scraps (trim off edges). Glue popscicle stick onto each picture for a handle. Ta-dah!
P.S. If you don't have the patience to wait for the glue / paste to dry, use a hot glue gun for the popscicle sticks and to attach the pictures to the cardboard. Just don't let the kiddos help with that part, of course!
