Sony is showcasing the capabilities of its latest water-resistant smartphones, in an underwater shop off the coast of Dubai. The store, which is four meters below the sea surface, will stay open for just three days. It's not any different than any other smartphone shop in that there's an assistant on hand to walk customers through the features of Sony's various handsets.

However, in order to shop there, you'll need to undergo a scuba-diving induction class first. But even if you're already a scuba diver, you'll have to accompanied on the journey down by a professional diving instructor.

And once inside you can remove your mask and breathing apparatus, as you see below.
