Dean Gunnarson is set to be buried alive for two days before staging an escape attempt.
The escape artist will been chained and bound and will have to survive two days underground locking in a steel coffin without water or food before trying to break out the casket, which will also be wrapped in chains with three tonnes of dirt on top of it.
Fresh air will be pumped into the casket through a hole so that Gunnarson can breath.
"I know that from a physical and mental stand point this will be my most challenging escape ever," said Gunnarson.
He is scheduled to be placed in the coffin at 7 p.m. on Oct. 29 and hopes to make his escape on Oct. 31 at 1:26 p.m., on the anniversary of Harry Houdini's death in 1926.
A camera will also be inside Gunnarson's coffin and people can watch him on large-screens at the Golf Dome, where the event is taking place. Admission to a family event at the site on Saturday is free with a donation to the Christmas Cheerboard.
