I was at MacDonalds in the weekend with my children and as we sat and ate one of my children looked down at the tray sheet and saw a picture of a bend chip on it. He said, 'I wonder if my chip is as long as that one?' He then proceeded to lay his chip on top of the other chip to check the difference in size. What happened then was a competition between all of us to select chips that we thought would match the size of the chip picture. This involved us making estimates (or guesstimates! which are educated guesses) about the length of the chips.
Who knew Maccas could be so educational!
