Fire

Forest Fire
When the gamemakers thought there needed to be more blood and exitment in The 74th Hunger Games, they created a forest fire to drive the remaining tributes to the lake, as they would get dehydrated, guaranteeing them to meet up and fight.

Outfits
All of Katniss and Peeta's outifts for the Games were inspired by fire. The chariot ride outfits were light up by Synthetic Fire, Katniss' interview dress looked as though it was being engulfed in flames as she twirled, at their Victor Crowning they both wore yellow outfits that represented candelight, etc.
