Using a pot, a speaker, and a bunch of straws, Leif Ristroph and colleagues at NYU are pushing the envelope of paper aircraft design. Their paper creations -- with shapes ranging from umbrellas to pyramids -- are pushed aloft by pulses of air created by a low-frequency tone from a subwoofer. Interestingly, the pulses of air give the aircrafts, which are not shaped at all like birds or insects, the appearance of flapping flight.
