Submission + - Gravity Defying Carpet very much possible ( 2

SK writes: "A flying carpet, just like the one in Walt Disney's creation 'The Arabian Nights' may soon be a reality. Laminarayan Mahadevan along with his colleagues at Harvard studied the aerodynamics of a flexible, rippling sheet moving through a fluid. Based on their study, the researchers came to the conclusion that making a carpet that would stay aloft in air may be possible. Mahadevan says that to stay afloat in air, a sheet measuring about 10 centimetres long and 0.1 millimetres thick would need to vibrate at about 10 hertz with amplitude of about 0.25 millimetres."
