Chinese 'Invisibility Cloak' Can Turn Fish Invisible

A team of Chinese scientists claims to have invented a gadget which can make fish 'invisible'.

The team from Zhejiang University said their device is able to direct light around an object in a tube, meaning it can't be directly seen.

The simple device is really just a five centimetre tall hexagonal cylinder, with a passage inside that looks transparent but actually directs light around it with mirrors.

Unfortunately it's a little crude right now - and clearly too small for humans. Still, any 10cm-long fish who want to avoid detection are in luck.

On the other hand, British researchers managed to come up with a method to make fish invisible decades ago - it's called dipping them in batter and frying them with chips.
