Scale Factor for Non-Surveyors

Have been pondering this weekend how I can graphically illustrate the effect of scale factor to non-land/hydrographic surveyors. Spent ages googling last night in vain and think I'll have to draw my own diagram. So how exactly do you explain to a non-surveyor that the distance you measure on the map/grid is not the same as that you measure on the ground?

On a lighter note I was pottery painting with my daughter on Saturday and fell in love with a teapot. Now just how sad is this?

Your South African wire globe, with a light bulb inside could be the ideal, and classic, teaching aid. Add a darkened room - voila!
