If you believe in gravity, then you know that if you remove air resistance, a bowling ball and a feather will fall at the same rate. But seeing it actually happen, in the world's largest vacuum chamber (122 feet high, 100 feet in diameter), is still a bit shocking.

In the late 1500s, Galileo was the first to show that the acceleration due to the Earth's gravity was independent of mass with his experiment at the Leaning Tower of Pisa, but that pesky air resistance caused some problems. At the end of the Apollo 15 mission, astronaut David Scott dropped a hammer and a feather in the vacuum on the surface of the Moon:
