In NASA’s Aquarius research facility, there are 2 waystations called Pinnacle and Gazebo, where divers can refill their oxygen tanks as well as catch a breather because they’re air pockets. Could anyone explain how these air pockets are created right in the middle of a lot of water, with no cave like formations or anything? If you search online the waystations, literally look like a mini gazebo/tent that is open from underneath where water passes, however if you stand underneath it, till your torso there’s an air pocket. It’s really weird to look at, seems almost magical and that’s why I wanna know how it works.

Air is lighter than water, so when they are in the same place air goes up and water goes down. Air and water aren’t smart though, so if they are going up or down and run into something, they don’t turn around to find another way. This is why cups work: the water could go over the side and fall out, but it’s not that smart. Underwater air pockets are just like upside down cups for air, since the air is trying to go up.
