Invisibility Cloak Is A Reality Now

Scientists at the University of Rochester have created an optical-illusion device they’re calling a sort of invisibility cloak.

It’s a stationary trick that bends light around smaller objects — rulers and pens are used as examples by these researchers — so that they seem to have disappeared. Four regular lenses are arranged like this:

If used correctly, you can see beyond the lenses but not what’s between them. Researchers have provided a video to show how it’s done. Physics professor John Howell and grad student Joseph Choi are calling it the first device with three-dimensional, multidirectional cloaking.

“There have been many high-tech approaches to try and achieve cloaking,” Howell said in a video. “We just figured a very simple way of doing that can just be using standard lenses and things that we would normally find in the lab.”

Here’s more information on how to make your own lens cloaking device.
