"Scientists in the UK have demonstrated a flexible film that represents a big step toward the "invisibility cloak" made famous by Harry Potter. The film contains tiny structures that together form a "metamaterial", which can, among other tricks, manipulate light to render objects invisible.

Flexible metamaterials have been made before, but only work for light of a colour far beyond that which we see. Physicists have hailed the approach a "huge step forward". The bendy approach for visible light is reported in the New Journal of Physics."
