Optical illusion goes viral but how long will it take you to spot it?
Eleanor Bailey was “crying” at this picture of her sister in a nightclub in the Netherlands (she’s the one with the red hair).
It’s been shared more than 5,000 times on Twitter but how long will it take you to work out why?

Some people see it immediately, for others it’s just total confusion.
Give up? We’ll give you a hand…
