The commonly accepted wisdom is that you can't fold a single sheet of paper in half more than seven times.
In January 2002, while a junior in high school, Britney Gallivan demonstrated that a single piece of toilet paper 4000 ft (1200 m) in length can be folded in half twelve times.
On December 4, 2011 seventeen St. Mark's students led by St. Mark's mathematics teacher Dr. James Tanton succeeded in setting a new paper folding record of 13 stable folds using just over __________ of toilet paper and the 3rd floor of MIT's famous Infinite Corridor. The St. Mark's folding team were the guests of the MIT's origami club OrigaMIT. The exercise dramatically demonstrates exponential decay as the __________ of paper, after 13 folds, is now 5 feet long and 2-and-a-half feet (__________ layers).
