Simple wrinkle free traveling
When I travel for business my dress clothes often get wrinkled in my suitcase. Instead of ironing (uses energy and I'm bad at it) or sending it out for dry cleaning (wasteful for clean clothes), I would like to create a balloon that was the shape of a shirt (or pants) that fit inside the item of clothing. It would attached to a hairdryer and inflate to fill the shirt/pants. With a few spritz of water the wrinkles would be "pressed" out from the inside.
