These drones drop burning balls in the forest to control wildfires

Breakthroughs, discoveries, and DIY tips sent every weekday. On July Fourth, amid a cacophony of fireworks and flame-throwing propane grills, a seemingly ordinary lightning strike hit somewhere in Grand Canyon National Park. The resulting spark ignited surrounding dry vegetation, and strong winds quickly spread the flames for miles. Over the course of several weeks, that initial spark has grown into a blaze engulfing more than 100,000 acres, officially classifying it as a "megafire" and the largest wildfire of 2025…so far. As of this writing, "The Dragon Bravo Fire" has already destroyed 70 buildings, including the historic Grand Canyon Lodge.
