But at least he’s taken the safety precaution of shielding himself with a piece of wood before hitting a mobile phone battery with a hammer.

Sporting shorts and sandals, this guy delivers one powerful strike to the battery as his friend films.

For around one second after nothing happens. Then suddenly it catches alight and explodes with such force it shoots into the sky like a rocket.

The guy squirms below as it comes crashing back to earth as a fireball.
