How does scuba diving work?

Explain scuba diving to me like I am six years old.
I am interested in scuba diving, but don't really understand the technical aspects-- why they use breathing gas different from normal air, decompression stops, nitrogen narcosis, etc. If you were telling a small child about how scuba diving works, as well as its main risks, what would you say?
