Take a quick look at the brand new Prometheus trailer, and help us figure out what these strange laser balls are that that one character's holding. On Saturday March 17 at 4 PM PST, Ridley Scott will premiere the first full trailer for Prometheus with the movie's screenwriter Damon Lidelof at WonderCon. After the premiere, the two will host a Q&A which will be available to the rest of the world (more details on that to come). But until then, what are these wonderful new space toys?
