Creative invention: With this disc you simply become invisible

The British start-up Invisibility Shield claims to have designed a camouflage shield that makes people invisible. The developers demonstrate how it works in a video. In fact, the people behind the camouflage shield seem to disappear. But how can that work? Lenses are arranged vertically across the entire surface of the newly developed camouflage shield, which reflect the light falling on them horizontally. The light is reflected horizontally in such a way that the object hidden directly behind the sign can no longer be seen. However, the developers emphasize that the shields work best against even backgrounds. In the video you can see that the functioning of the sign is always demonstrated in front of symmetrical backgrounds with horizontal lines. Nevertheless, the start-up’s project is well received. The developers are looking for financial support on the crowdfunding platform Kickstarter. Originally they wanted to take about 6000 euros. In the meantime, however, more than 1,200 people have donated a total of over 229,000 euros for the realization of the project. The start-up wants to sell the camouflage shield worldwide as early as December of this year.
