Invisibility cloak is about to be used for teaching

In the future, stealth technology will be introduced into physics at many schools around the world.

Invisibility technology will be put into teaching

Nowadays, the problem of lack of practical experiments at schools when teaching science is the reason why subjects like physics become the nightmare of many students. This problem will soon be solved when German scientists are racing against time to bring Harry Potter invisibility technology into teaching.

Schools around the world will soon own this "made in Hogwarts" technology

Accordingly, the team from the Karlsruhe Institute of Technology (KIT) has created an invisibility cloak capable of making small objects invisible in the human eye. With its small size, this invisibility tool is well suited for visual models in the classroom.

In essence, this cloak is a container covered with light-emitting acrylic paint. On the box is a small cylindrical tube made of polydimetylsiloxane - a phase compound of titanium dioxide nanoparticles that helps disperse light.

The left tube is covered with acrylic paint and special organic material so we can't see the shadow of the inside

When a random object is inserted into a stealth box, light striking the object will be bent by scattering. As a result, light waves travel longer and unfocused distances.

Thanks to acrylic and polydimetylsiloxane coating, light shines on objects that are bent and move in a random zigzag (right)

At the same time, people have the characteristics of only seeing an object when light is transmitted from the object to the eye. Therefore, the phenomenon of bending and slowing down the path of light will cause the object to stealth right before our eyes.

With this invention, experts hope to bring them into teaching schools will inspire and love chemistry for future generations.
