Place four toothpicks on the outline of the goalpost below.
Note that in this position
the football is in the middle of the upright arms.
Challenge 1: Move three toothpicks and reorient the goalpost
so that the football is
no longer in the middle of the goalpost's arms.
Challenge 2: Replace the toothpicks in their original positions. Now, try to do the same thing by moving only two toothpicks.
