Fun wind up butterfly that's easy to build. Use a 30mm rubber band and surprise your friends!

How to Build and Fly

1 - cut out a little washer, can use any smooth material (e.g pop can, smooth plastic)

2 - assemble in this order top wing → washer → body and put the hook through all of that

3 - use any sort of glue to attach hook to the top wing

4 - slightly bend wings in one direction, e.g both wings bent right

5 - wind up ~30 times and watch it fly
