Make your own metallic masterpiece of a costume with a few household odds and ends.
HEAD: With a craft knife, trim the bottom and the handle off the milk jug. Fit it over the hat (diagram 1) and secure it with duct tape. Tape a snack cup to each side of the cap. Cover everything with the foil tape. Use loops of duct tape to attach eyes and a mouth (see ideas above).
BODY: To make a shoulder strap, cut 2 (21-inch) lengths of duct tape and stick them together. Repeat for the other strap, then tape the straps to the insides of the roasting pans (diagram 2).
Add decorations (such as those listed above), securing them with the foil tape (diagrams 3, 4).
Have your child put on the sweatshirt and pants. Using the wire cutters, snip the dryer duct into 4 lengths that fit comfortably on your child's arms and legs. Secure them with duct tape as needed. Apply strips of foil tape to your child's pant legs, gloves, and shoes.
