Your kitchen faucet can shoot flames

Tap water that catches fire is caused by methane gas leaking into underground aquifers. This gas hitchhikes on the water as it travels up through the pipes and escapes into the air the moment you turn on the faucet.

This phenomenon often happens in areas with specific geological formations where pockets of natural gas sit directly beneath the water table. When the seal between these layers is broken-sometimes naturally, sometimes through human activity like drilling-the pressurized gas forces its way into the water supply.

The water itself isn't burning; it's the gas bubbles escaping from the liquid that ignite. It creates a surreal visual of a blue and orange flame dancing on top of a running stream of water. However, having a flammable faucet is a serious hazard, as the gas can build up in poorly ventilated bathrooms and lead to explosions.

While most people associate this with industrial accidents, documented cases of flaming wells exist in historical records long before modern drilling. In some regions, the ground is so saturated with ancient organic matter that 'eternal fires' have burned in riverbeds for centuries.
