The Nightmare Fear Factory in Niagara Falls, Ontario, makes the most of Halloween every year, during which time it takes a hidden camera to capture the natural expressions of fear that visitors make when they are in a haunted house, which is very vicious. It is rumored that the haunted house was transformed from an old coffin factory. It takes about 15 minutes to walk completely, and if you quit halfway, the haunted house will add your name to the public "coward list."
