Man made underwater air pockets

355 views

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.

You can replicate this with an empty glass and a sink or bathtub full of water.

Just invert the glass and lower it (vertically) into the water. You’ll create an air pocket in the submerged glass.

Since the air is lighter than the water, it tries to float straight up. But since the glass blocks it from going up, it’s stuck there.
