Swallowing swords, stretching their skins until you're forced to turn away, this is the world’s most stupendous collection of human oddities.

This eclectic sideshow cabaret, hailed 'the Coney Island Freak Show for the 21st century', has been specially commissioned for Priceless London Wonderground and pushes the boundaries of what the human body can achieve.

Marvel at Gary Stretch - owner of the world's stretchiest skin (above), or wince at the Space Cowboy, the holder of 11 Guinness World Records, the most recent of which saw him swallow 18 swords in one go.

This smorgasbord of strange is on display at the Southbank Centre until September.
