What fule do fire eaters use?

Fire eaters typically use a high-proof alcohol, such as ethanol or methanol, as their fuel. These substances burn at a lower temperature and can be extinguished quickly, making them safer for the performance. The fire eater swallows a small amount of the fuel and then expels it to create a flame, but it is crucial for them to practice safety precautions to avoid burns or inhalation hazards.
