Video: Underwater lightsaber battle at Star Wars weekend

A US aquarium held a Star Wars weekend from May 2-4 - including the Monday to take advantage of the 'May be the fourth be with you' phrase, popular among fans.

The event at the Audubon Aquarium of the Americas in New Orleans saw divers donning Darth Vader, Yoda and Darth Maul costumes to take part in a lightsaber battle underwater, which you can see in the video below.
