So easy and so clever. Dress appropriately geeky, pick up a travel-sized Scope bottle from your local drugstore, supermarket, or Target/Wal-Mart, empty the mouthwash bottle (maybe use some, fresh breath always makes a great impression), tie some string around the neck of the bottle to create a necklace, slip it on, and voila! You’re done.
What’s your great costume idea?
