Working tractor beam can move objects 5 feet with just light

http://www.popsci.com/science/article/2010...-objects-5-feet


Have you ever lazily wished you could just use a tractor beam to grab that out-of-reach object? Apparently, you can.


Using only light, Australian researchers say they are able to move small particles almost five feet through the air. It’s more than 100 times the distance achieved by existing optical “tweezers,” the researchers say.
"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."
