Harry Potter-like invisibility cloak makes animals disappear

London: Scientists have created an invisibility cloak just like the one depicted in the ` Harry Potter` movies. In a video footage of the device in action, a goldfish suddenly appears as it swims out of a cloak submerged in a tank of water and then the lower half of a cat disappears as it steps inside a cloak placed on a table.

According to the scientists, when swimming inside the cloak, the goldfish becomes invisible and does not block the scene of green plants behind the cloak. The cloak, which was developed by scientists at Nanyan Technological University in Singapore, uses panels of glass to make objects invisible by bending light around them, the Independent reported. The researchers said that the cloaks can be adjusted to make objects disappear from any line of sight. They added that the devices could have important "security, entertainment and surveillance applications." However, the basic device can only make objects vanish from certain angles and the cloaks are partially visible. ANI
