To Do Zero-G Experiments On Earth, You Need A Massive Vacuum Chamber

Excited for the August 21 eclipse? Visit our Eclipse 2017 page to explore the science, history, and myths of the event. The Curiosity team will be viewing the eclipse alongside NASA in Carbondale, Illinois. Follow us on Facebook for live videos, trivia, and interviews on the big day.

How can you experiment with the effects of zero-G without launching into space or flying a plane in stomach-lurching parabolic patterns? With a really, really big vacuum chamber, of course. Luckily, they have one in Bremen, Germany. Watch how it works in the video below.
