Scuba atmospheres
The air spaces in their ears, mask, and lungs become like vacuums as the compressing air creates a negative pressure. Delicate membranes, like the ear drum, can get sucked into theses air spaces, causing pain and injury. This is one of the reasons that a diver must equalize their ears for scuba diving.
