The sudden ignition of a hydrogen-filled balloon near a hair dryer can be explained through electrostatics and combustion physics. While hydrogen gas requires a temperature of about 560 °C to ignite, the heat from a typical hair dryer alone isn’t sufficient to reach this threshold. However, hair dryers generate fast-moving air, which increases friction between air particles, dust, the plastic casing, and even human hair. This motion can build up static electricity on surfaces. When the balloon (containing highly flammable hydrogen) comes into contact with the charged dryer, a small electrostatic discharge (a spark) can occur. Despite its tiny size, this spark has enough energy to ignite the hydrogen gas, causing an immediate and dramatic combustion.#science #physics #learning #explained #facts #staticelectricity
