Very few people get the chance to experience the effect of a zero gravity experience. When the team over at the Northrup Grumman Foundation invited me to go up on a zero gravity plane, I jumped at the chance. All they asked is that I think about an interesting experiment to try in a weightless environment. I told them I didn’t have to think about it; I wanted to release 2,000 ping pong balls. Amazingly, they agreed!
