When you hear the word 'festival' you probably instantly think of Coachella or Glastonbury. One of the very last things that will ever come to your mind upon hearing the word is Mexico's 'exploding hammer' festival.

As wild as it sounds, the festival sees participants smashing hammers with a mix of sulphur and chlorate attached to the ends. Participants smash the hammers against rail beams, causing them to explode and smoke.

San Juan de la Vega, a small town in Mexico, is famous for the festival, which is dedicated to St John the Baptist - who is said to be the town's 'Robin Hood.'

This year, a whopping 6,000 people attended the festival including spectators. Over 100 police officers were also present as well as ambulances to care for the inevitably injured. Over the course of the festival, 43 people have been injured.
