Tin foil is one of the most pliable materials for costumes, particularly if you are short on time and resources. It can be molded into almost any shape without disintegrating. You can create ornaments and elaborate masks. Since the tin foil provides the illusion of silver, it can cover boxes and tubes for body armor and robot parts. Tin foil can accommodate smooth or wrinkly surfaces, and can be used as a sheet or crunched into a handle.
Wrap the jeans, jacket and gloves in duct tape. Do not change their shape. Cover the clothes with the tape as if you are painting them.
Wrap the boots with duct tape. Make sure you can get your feet in and out of the boots.
Cut a hole in the top of the cardboard box that is big enough to pull over your head. Cut holes on the right and left side of the box for your arms to slide through. Cut the the bottom flaps of the box off.
Cover the cardboard box in aluminum foil. Tape any loose edges down with duct tape. Do not cover the holes for your head and arms.
Wrap the funnel in duct tape. Use bobby-pins or a clip to hold it in place on your head.
Spray your face with the silver paint.
