The 15 students from St. Mark's School in Southborough executed the feat Sunday in the so-called Infinite Corridor, an 825-foot hallway that connects many of the main buildings at the Massachusetts Institute of Technology.

Of course we had to try." Tanton has been organizing attempts to break the record for five years. This year, he got MIT's origami club, OrigaMIT, to gain him the use of the corridor, where they would be free of wind interference. While the Guinness Book of Records does not keep track of paper folding, Tanton believes his class deserves a Wikipedia page at least. He said the class will try again next year with 24,000 feet of paper. Read More Boy to launch Peep into upper atmosphere Royal wedding doughnut, cake to go on sale 50 people care for baby orangutan
