diving bells

A diving bell is a rigid chamber used by divers to explore underwater environments at greater depths safely. It works by trapping air or a breathable gas inside, creating an air pocket that allows divers to breathe and work while submerged. The bell is lowered underwater on a cable and remains connected to the surface or an air supply, enabling controlled breathing and communication. Its structure withstands water pressure, and it often has openings for tools or managing underwater tasks. Diving bells are essential for underwater construction, research, and salvage operations, providing a safe base beneath the water's surface.
