Researchers Create Real Tractor Beams

Gadgetank writes "Researchers out of the Australian National University have created a device, working in conjunction with other necessary devices, that can literally move small particles with light. And only light. The way it works is by shining a hollow laser beam around some tiny glass particles. The researchers heat the air around the particles, and therefore cause the dark center of the beam to remain cool."

If you're the kind of douche who likes to make shit up in order to impress people - or just an idiot who confuses ignorance for knowledge - no, you probably won't have a very good time when I'm around. But I guarantee that everyone else will deeply enjoy laughing at you. So "fun" is a relative term.
