Dive the Marianas Trench
The deepest spot in the earth’s oceans is the Challenger Deep in the Marianas Trench in the western Pacific, at 10,994 meters. The BBC has a magnificent interactive graphic of the Trench. Pause as you descend to play the clips at various depths. (And yes, you’ll see the same CIO dating commercial at every stop!)
