A Feather and a Bowling Ball Dropped at the Same Time Inside the World’s Largest Vacuum Chamber

Physicist Brian Cox of the BBC Two program Human Universe visited the world’s largest vacuum chamber at the NASA Space Power Facility outside of Sandusky, Ohio, to demonstrate the effects of air on falling objects. In the video, a feather and bowling ball are dropped at the same time in normal Earth conditions and after the air has been removed from the room.
