Invisibility Cloaks

Available for over a year

Harry Potter has one, so does the Starship Enterprise, and now scientists in the UK and the USA claim that you could have one too. The invisibility cloak is no longer stuck in the realm of fantasy, but is soon to become a reality. Peter Evans talks to the researchers who have engineered an entirely new material that can make objects virtually undetectable, and looks at the extraordinary possibilities that this kind of invisibility might offer.
