Remember that this is a fluid, rotating motion.
1. Begin with face 1 (pink) facing you. 2. Push both the right and left sides downward. The profile should look like a mountain peak. 3. The first new face, face 2 (blue), will be revealed from the center of the flexagon; with your thumbs, open it up like a book. 4. Repeat Step 2 to reveal face 3 (yellow, second new face). 5. Return to face 1 by reversing the fluid movement. You will be flexing the outside edges toward the center. The profile should look like a V-shape.
NOTE: A second method of returning to the starting point is by flipping the flexagon over so that face 4 is facing you and flexing it twice. Then flip it over once more and face 1 will be facing you.
