Gravity is a funny thing. You're never really free of it -- it's one of those pesky fundamental interactions that pervades the entire universe. There are ways to avoid it, though, for just a few seconds.
These photos, created to promote the launch of Alfonso Cuaron's Gravity on DVD and Blu-ray, were captured by Cal Mero at the Brunswick Baths. A dedicated underwater hair and makeup artist was on hands to adjust models' locks and jocks, and underwater assistants dressed in black to hold props in place.
Mero says setting up and snapping the photos wasn't as difficult as you'd think: "“Taking good photos underwater isn’t as hard as it looks. Although the models I work with are incredibly talented, getting that floating, zero gravity shot is as simple as controlling your breath."
Of course, none of these really stand up to the majesty of another kind of low gravity; Kate Upton's pioneering scientific efforts put even Sandra Bullock and George Clooney to shame.
