Butter-Fly Flippers are great butterfly toys for kids and fun. They are great pranks for kids as well! Put inside a book or box. When it opens they start flapping around. They are a very fast print, very thin. You will need a rubber band and I personally suggest using a paper clip or if you have it, piano wire to make a hook to put the rubber band in. You want a thicker smaller rubber band with a lot of strength to store more energy for the flipping. They are a ton of fun.
