James Tanton, of the St. Mark's Math Institute at St. Mark's School in Southborough, Massachusetts, makes excellent short mathematical videos.
He and his students also folded a very long piece of paper 13 times -- that is, they created 213-ply toilet paper. This is a world record. (There's a bit of a question about whether they actually got 13 folds or just 12 -- the 13th fold has to be held in place. 12 has been done before.) You can read about it in a local newspaper, or see a video on Youtube. They did it in the "Infinite Corridor" of MIT, which is not infinite but is very long, about 800 feet. On a Sunday, apparently, and on what must be the third or fourth floor. They got access thanks to OrigaMIT, MIT's origami club. I am only very mildly surprised that such a club exists.
This whole thing may be the only known good use of single-ply toilet paper.
