British start-up Invisibility Shield Co. has revealed that it has created a 6-foot-tall “Megashield” being sold for $828 — which they claim can make multiple people invisible, like something straight out of a “Harry Potter” film. The shields utilize ultra-large, precision-engineered lens arrays, which form the face of each shield and redirect light that reflects off the person standing behind the shield, away from the observer. The shape and placement of these lenses then cause background light from either side of the shields to spread over the apparatus’ face and be directed toward the observer instead, effectively making whatever is behind disappear in plain sight. However, the technology does not blend into its surroundings perfectly and does create a blurred block. Each unit is fully waterproof, does not require any power, and is constructed from 100% recyclable materials, according to the company.
Soooooo...basically, they've invented a wall that you can hide behind?! Wow! Science people!!
