I'm not the type to freak out about all the latest advances in high-tech gadgetry, but an authentic, fully-functioning invisibility cloak is one invention I would definitely wait in line for days to buy. Yeah, yeah, I know what you're thinking: Where does this lunatic go shopping, Diagon Alley? But thanks to a team of electrical engineers at Duke University, the idea of an invisibility cloak like the one Harry Potter used to roam around Hogwarts unseen may be one step closer to becoming a real thing.
No joke! Apparently engineers have been working on the "cloak" for six years, and while it's not finished yet (hey, these guys aren't wizards), the prototype shows promise. Or, in grad student Nathan Landy's words:
"We built the cloak, and it worked. It split light into two waves which traveled around an object in the center and re-emerged as the single wave with minimal loss due to reflections."
