Washington, Nov 21: With rapid advances, Harry Potter invisibility cloak would soon be a reality, however, the nearest possibility depends upon will and the money put into the project, says an expert.
Scientists have long been studying optical properties needed for an invisibility cloak.
But when asked about how real is the possibility of an invisibility device, Ulf Leonhardt, a visiting professor at the National University of Singapore failed to make a guess.
"I think it''s a question of the will and the money put into this field," National Geographic quoted Leonhardt, as saying.
