How To Get To The Sea Floor While Still Breathing

Before we had ALVIN — or proper submarines for that matter — the best way to get to the seafloor was by using a diving bell.

When you're done diving into these, check out a few decommissioned subs, their claustrophobic torpedo rooms, and these nine bathing machines.
