The Hammer and the Feather

Legend has it that Galileo dropped two balls with similar volume and different masses from the leaning tower of Pisa. Whether Galileo really dropped the balls from the leaning tower of Pisa or not is debatable. And of course, physics has shown us that the two balls would reach the ground at the same time. Especially in a vacuum, where the shape of the object wouldn't matte. In this video, the Apollo Astronauts drops a hammer and a feather in the vacuum of the surface of the moon to finally answer the old age question once and for all.
