Invisibility Cloak

An invisibility cloak is a piece of equipment that makes oneself appear invisible. Invisibility cloaks were thought to only be real in fictional books and televsion programs, but modern sciences have created a couple different types of materials that seem invisible.The first type of invisibleity cloak is made out of carbon nanotubes this type they use the same phenomena as mirages. The material is heated via electrical stimulation the sharp temperature difference between the cloak and the outside world this causes the light to bend away from the material. The only problem is the biggest sample of this is made inside a petri dish. Metamaterials are another substance used this substance is smaller than the wavelength of light this forces the light around the object making it appear not there. This material is only found ten micrometres long. There is also a technology where you can use the green screen and imbed yourself in whatever the background image is. Invisibility cloaks are all about bending light so that you can't see the what the light is getting bent around, which is what is under the cloak. The invisibility cloak is still small but scientist think they will be able to perfect this technology one day the link below has a video to watch [] [] Tanner Syroteuk
