Product Description: Product introduction: This product is a magic butterfly that can fly. The operation method is simple. Hold the tail of the butterfly with the left hand and rotate the head of the butterfly about 40 times with the right hand. At the same time, release the hands or clip it in the book to let friends open the book, and then you can see the butterfly flying out. This product is similar to the spring toy, not to highlight how far it can fly, but to show the function and dynamics of flight. It is not really able to fly. It is an upward force generated by the torsion of the rubber band. It will fall down after the torsion of the rubber band is released.
