In China, a group of scientists from Donghua University presented a breakthrough for an invisibility cloak that could work like Harry Potter’s.
The Faculty of Science at Donghua University announced that they were working on a kind of invisibility cloak and even compared the technology to the invisibility cloak used by Harry Potter.
One of the most creative inventions of JK Rowling’s franchise was the invisibility cloak that made its first appearance in the first Harry Potter film and although it is essentially impossible, science could now prove otherwise.
Beyond a cape or a garment, it is a sheet that uses science to divert light from what the eyes capture.

The director of the faculty, Chun Junhao, physicist and director of Donghua University, presented the most interesting and curious advances about the project at a scientific event in Shanghai.
In Junhao’s own words, “in the future it is possible that everyone will have an invisibility cloak in their closets.”
How does the invisible cloak work?
In the presentation of the advance, two people helped the professor explain, holding a sheet, that when held horizontally it is transparent and shows what is behind it.
A few seconds later, the subjects placed the sheet vertically at a 90-degree angle, thus making the director’s legs disappear completely.
Junhao explained that what he did was not a magic trick, but that the sheet in question was made up of a grid of small convex cylindrical lenses.
These lenses manage to change the direction of light so that the images behind the sheet become too small to be perceived by the human eye. This creates the effect of invisibility.
