The municipality of Tultepec in Mexico produces about half of all of the country's fireworks. Every year, more than 100,000 people flock to the area for a nine day event called the National Pyrotechnic Festival. There are activities common to a fair (e.g. food, music, dancing), but the biggest reason people attend is to experience the dazzling firework displays.
Photographer Thomas Prior traveled from New York to attend one of these festivals, and ended up capturing a collection of beautiful photographs showing people partying from within explosions.
