You may or may not have heard about the contest Six Flags is hosting for this spooky season. If you haven’t, Six Flags in St. Louis is allowing people to lie in a coffin for 30 hours to win $300 and other prizes from the theme park called the “30-Hour Coffin Challenge”

Six people have already beat the challenge, won the $300 and other prizes like season passes to the theme park.

Contestants; Brian Johnson, Keith Richter, Matt Daley, Olivia Crabtree, Stacey Wagner, and Stevi Rogers started Saturday at 1 p.m. “laying to rest ceremony” to Sunday 7 p.m. “raising from the dead.”

Each contestant had 6 minute bathroom breaks every hour and a small break for food, which Six Flags provided.

Brian Johnson, one of the contestants, wrote on Facebook: “It was very difficult. Cold as hell. Bathrooms were so far away you had to run to get there and back in the 6 minutes,” he continued to say. “The open top was brutal. Lights everywhere, people talking, you could barely sleep.”

When the challenge was over they received their prizes and even got to keep the coffin that they slept in.
