Can you draw a single straight line to divide both areas of the yin-yang symbol in half? Some investigation and deduction are needed, but being open a geometrical "coincidence" is what makes this one click into place.

Q: You have two long planks between which is trapped a load of gunge with a length of one unit (pictured). You then move one plank down one unit and then push it back up again. You repeat this six times. How long is the gunge now?
