This video was shot during a flight on a modified plane that simulates microgravity using parabolic flight. In addition to being able to simulate zero gravity (really freefall) the pilots have the ability to simulate other gravity affects like the gravity of the Moon and Mars. I thought it would be fun to be the first person to juggle in lunar gravity. Needless to say, everything falls much slower, making juggling much easier...and funner!
