Six Flags St. Louis is holding a unique contest that claustrophobic park-goers will want to avoid. Contestants who stay in a closed coffin for 30 hours will win some cool prizes.

The contest is being held on October 13th and will have six people competing in the Fright Fest 30-Hour Coffin Challenge. They will be given bathroom breaks, but will be disqualified if they leave their box for any other reason.

Friends can tag along during normal operating hours, contestants are on their own after the park closes.

Those who make it through the 30 hours are put into a drawing for a $300 prize, two 2019 Gold Season Passes, a Fright Fest prize package, two VIP Haunted House passes, and a ticket for two to ride the Freak Train. On top of those prizes, the winner can take their casket home with them.
