An S.S. Adams Invention! Wind it up, flies up to 20 feet in the air. Use again and again.
This is great for kids, or for scaring the crap out of people! For example, wind it up, and place it inside a book. Set the book on a coffee table, or hand it to a spectator before doing a book test routine. When they open the book, the butterfly will fly into the air, and freak people out!
