Hats off to scientists in New York, who have managed to produce a cheap “invisibility cloak” effect using readily available materials and a lot of clever thinking. Through a combination of optical lenses, any object that passes behind a certain line of sight can be made to disappear from view.
“People have been fascinated with cloaking for a very long time,” said John Howell, a Professor of Physics. “It’s recently been a really popular thing in science fiction and Harry Potter… I think people are really excited about the prospect of just being invisible.”
“From what we know this is the first cloaking device that provides three-dimensional, continuously multidirectional cloaking. I imagine this could be used to cloak a trailer on the back of a semi-truck so the driver can see directly behind him. It can be used for surgery, in the military, in interior design, art.”
What makes this system so interesting is that it’s simple, inexpensive and capable of working at multiple angles, as long as the object remains inside the series of lenses. It cost the scientists $1,000 to get all of the necessary equipment together, but it can be done more cheaply. A patent is pending for their invention but the scientists have put together instructions on making your own Rochester Cloak at home for less than $100.
