Ghost skin

Okay kiddo, do you remember how our skin is the outer layer of our body that we can touch and feel? Well, animals such as octopuses, squids, and certain fish have skin that can change color and pattern to blend in with their surroundings. This ability is called camouflage and helps them hide from their predators.

Now, some scientists have developed a new kind of material called "ghost skin" that is inspired by this camouflage ability of animals. This material can change color like an octopus and become invisible in a specific background.

To make ghost skin, scientists used tiny particles called "nanostructures" that reflect and absorb light in a certain way. When placed on a surface, they can change color and appear invisible depending on the color and pattern around them.

By using ghost skin, scientists hope to create new materials that can be used in things like clothing, accessories or military uniforms that can blend in with their surrounding environment, making them less visible to the naked eye.

So, just like how an octopus can hide from its predators, with ghost skin we can create things that can blend in and be invisible in their environment. Cool, huh?
