Freebee Friday: Under the Deep Blue Sea

James Cameron, better known for Titanic and Avatar, recently went on a sea journey to the deepest part of the ocean. Nearly 7 miles down in the Mariana Trench, his one-man sub, Deepsea Challenger, took him to see things few humans have seen, and recorded it for all to look at and marvel. The video is a great science lesson about not only what lurks way down under and how you get there, but what you need to do to get back to the surface safely.
