I agree with both you and the parent post. The article definitely asks for the suspension of disbelief and to be treated like a math puzzle. However, I think it would be a valuable exercise to try and make a more formal statement of the situation so that the parts of the problem that don't line up squarely with the premise (i.e. eggs often crack when dropped from ~4ft high) were more explicit. That way, the problem could be introduced both ways at the outset, so that you have the motivating image along with the actual constraints of the problem.
