Students in Pisa built the world's largest paper airplane — and it actually flew into the record books

Every schoolchild knows the paper airplane. A team of students at the University of Pisa decided to ask how big one could get — and kept folding, testing adhesives and refining the engineering until their giant creation earned an official Guinness World Records title as the world's largest paper airplane. The project drew in an Italian content creator who carried it to a wider audience, but the heart of it was student teamwork: years of testing, failed launches and small fixes, until the biggest paper plane anyone had ever made took its record flight.
