Paper Can Only Be Folded Seven Times
It may not have taken a large chunk out of the daily curriculum to discuss, but there is a very good chance that, at some point during science, the topic of folding paper popped up. It was once believed that paper could only be folded seven times before the energy needed to complete a crease became impossible to exert. With a standard piece of 8x11” (20x27 cm) paper, the surface area for the fold becomes too small to continue folding, but with larger samples, more than seven folds are possible – if not incredibly difficult. As MythBusters proved, it requires a little mechanical help to fold a football-field sized sheet of paper 11 times.
