Not sure what to do with that extra piece of paper after cutting a square out of an A4 or a Letter size paper? Learn how to fold this cool Spinning Rotor designed by Didier Boursin. When you let it fall, it will start spinning like a helicopter. Try it out! it is pretty fun. Especially if you have stairs at home. Enjoy! Thanks for watching! Wilson Lee @Heap Art
