The public is being asked to make a slightly unusual contribution to a tourist park's new attraction - smelly pee.
Thorpe Park in Surrey is eager to introduce a "signature stench" to its horror maze SAW Alive which opens next month.
In a "contest" on Friday, members of the public will be offered a £500 cash prize to produce the most pungent-smelling urine.
The smell will then be used alongside other stenches in the maze.
The job of selecting the smelliest sample falls to Thorpe Park's entertainments manager Laura Sinclair.
She said: "We want SAW Alive to be as authentic and terrifying as possible to make visitors feel as if they are living in a real-life horror film.
"To do this we need to really push the boundaries of what our guests experience from a sensory point of view."
