Fire breathers are performers who create the illusion of breathing fire by expelling a flammable liquid from their mouths and igniting it. This art form requires extensive training and safety precautions to prevent serious injuries. The liquid used is often a type of kerosene or lamp oil, which burns brightly when ignited. To perform, fire breathers typically take a small amount of the flammable liquid into their mouths and then blow it out in a fine mist over a flame. The technique relies on proper timing and control to create impressive fireballs. Many fire breathers also incorporate elements of circus or street performance into their acts.
