How do you make a w made of 4 pens into a perfect square by only moving one pen

To make a letter "w" out of 4 pens into a perfect square by moving only one pen, follow these steps:

1. Start by arranging the 4 pens in the shape of the letter "w" on a flat surface.

- Take 2 pens and position them in a V shape, with the ends touching each other forming an acute angle.
- Place a third pen horizontally across the bottom part of the V shape, connecting the ends of the V.
- Finally, diagonally position the fourth pen on top of the third pen, crossing over the V shape.

- Gently slide it towards the pen placed diagonally on top, creating a square shape.
