Only In Greece 1 - Flour War in a Small Greek Town

In a small Greek town, villagers engage in a unique annual event known as the flour war. Participants don protective gear and use over 1500 kilograms of flour, tinted with food coloring, as their weapon of choice. The event is a fun-filled day for most, though it poses risks for those with respiratory issues or gluten intolerance. The battle begins with cowbells, as villagers split into rival gangs and hurl flour bombs at each other, aiming to cover their opponents in flour. The cleanest team on the other side of the river is declared the winner.
