In high school we used to receive printed notices aka 'circulars' from administration to give our parents (do they still do this?) -- our classroom window overlooked a cabin used for temporary classes with a corrugated asbestos roof. After promptly turning my circular into a plane and flying it out the window, exclaiming "hey i got to the 5th row on the cabin roof!" Thus began the hottest aerodynamics contest in my academic life, we experimented with so many designs, tried all kinds of crazy modifications. The interesting thing was, our classroom window was an entire story higher than the cabin roof -- the usual "paper plane contest hack" of rolling a paper ball and chucking it as hard as you can was not very good compared to a functional aerodynamic design with some lift. The "contest" ended when a week later someone reported our antics and the school was aghast to find 40-odd paper planes roosting on the portacabin roof and our entire class was given some stern warnings but luckily noone sold me out as the instigator.
