If it were physically possible to fold a piece of paper in half 50 times (it's not), how thick would the resulting origami sculpture be? Quick! No fair calculating. What does your gut say?
If you have absolutely no idea, I'll tell you that a standard piece of printer paper, folded six times by high a school student with very little concern for symmetry or crease definition, has an average thickness somewhere between six and eight millimeters. How much will that increase over the next 44 folds? Any ideas?
