Among all the superpowers that children fantasize about having, one of the most repeated over the years is being invisible. Until now, this ability was unique to fantasy series and movies, however, a group of engineers from the Faculty of Sciences at Donghua University (China) has managed to make this goal a reality, but not using magic, but through The science.
It was almost a month ago when Chu Junhao, physicist and director of the faculty we just mentioned, presented one of the most interesting and curious advances we have seen this year during a scientific event held in Shanghai.
This is the presentation of one of the advances that this university in China is working on the most, invisibility , and just as if it were a Harry Potter movie, during the presentation this academic referred to¡’00 the project as ” a cloak of invisibility.”
With the help of two people, Junhao came out on stage with a sheet that was initially translucent, since his legs could be seen from behind, although somewhat blurry. But the spectacular thing did not come until the assistants turned the sheet at 90º and the physicist’s legs disappeared.

As Junhao himself explained, this is not a magic trick but rather this sheet was composed of a grid made of small convex cylindrical lenses that manage to change the direction of the light, making what is behind them images that are too small to be perceptible. to the human eye, thus creating the effect of invisibility.
For now this is only a project developed at a university, but its creators do not want to fall short of the magnitude of their discovery and as the academic himself stated “in the future, everyone will have Harry’s invisibility cloak.” Potter in the closet.”
The truth is that after these statements alarm bells go off a little about this advance, since in the absence of examples , the mind only leads us to the bad uses that could be made of this “invisibility cloak”, in addition to the fact that up to the At the time, the development of this technology was focused on military uses , such as creating a layer for combat aircraft or making military cars undetectable.
