1. Fold the dollar bill in half and then unfold. Now fold the top right-hand and left-hand corners to the center crease, creating a triangle. Flip the bill over.
2. Fold the two sides so they meet in the center, but as you do it, pull the flaps from behind so that they form two triangles. Flip the bill back over.
3. Fold the top of the bill down to match where the two flaps meet at the bottom.
4. Next, fold the top up so the crease matches the fold line underneath. Flip the bill over.
5. Take one of the bottom sides and fold it slightly underneath itself to create a smaller, secondary wing. Do the same to the other side.
6. Fold the two sides in half from behind and then fold them back out again at the wings to give your butterfly a three-dimensional shape. Now let it fly—but not too far.
So now you know how a buck butterfly is made, but what about the buck itself? Read about the pain-staking process here, then watch this video to see the money-making action unfold.
For years, people thought you couldn’t fold a single sheet of paper more than seven times. Boy, were they wrong. The crew from Mythbusters folded an (admittedly gigantic) sheet 11 times while this 15-year-old folded one 12 times.
