Hammer and Feather Experiment on the Moon

Galileo did experiments to prove that heavy objects and lighter objects will fall at the same rate. This meant that, taken to extremes, a hammer and a feather should fall at the same rate. However, a feather tends to float slowly because of air resistance. During the Apollo 15 moon mission in 1971, astronaut David Scott had the perfect opportunity to prove Gaileo's point, because there was no air to cause drag on the feather. And some falcon on earth never knew how far a part of him flew. How about that? (via reddit)
