Japan’s Hidden Fire Defense System

This hidden water gun system was made for something special. In one village in Japan, where centuries-old farmhouses still stand, they built sprinklers that stay tucked away until there's a fire. Once flames are detected, water shoots out automatically to protect the wooden homes. And twice a year, they test the whole system in full display, turning it into what's known as the Water Hose Festival.
