A group of adrenaline junkies stripped off to board the ride in Essex, to try to set a world record. Fifty-seven daring individuals got naked and hopped on the Green Scream at Adventure Island in Southend.
In 2010, 102 people in their birthday suits set The Guinness World Record on the very same rollercoaster.
While they couldn't top the record this time around, the brave 57 celebrated the event's five year anniversary in style.
They even raised £10,000 for Southend Hospital Charitable Foundation's Keyhole Cancer Appeal.
Lucy Thomas-Clayton, from Southend Hospital Charitable Foundation, told the Mail Online: "It takes a lot of nerve to take off all your clothes in front of complete strangers, plus the world's media - so we would like to say a massive thank you to everyone who was brave enough to bare all and raise such a huge amount of cash for our vitally important cause."
