This Is The ANCIENT FIRE That Has NO SMOKE #history #facts - Video

Imagine you are being HUNTED across the windy plains, and you need a fire to survive—but a single puff of smoke will give away your position and lead to your D*ATH. To stay HIDDEN, Native American tribes developed a genius design called the Dakota Fire Hole. Instead of building a fire on the surface, they dug two specific holes. The first is the main chamber where the fire sits deep underground, TRAPPING the light so it can’t be seen from a distance. But fire needs oxygen, so they dug a second, angled tunnel upwind. EDUCATIONAL part: This creates what engineers call the VENTURI EFFECT. As the fire heats up, the hot air is forced upward, creating a vacuum that SUCKS fresh, cold oxygen through the secondary tunnel. This constant flow of oxygen feeds the base of the fire, causing it to burn so hot that it consumes its own smoke, making the fire nearly INVISIBLE to anyone nearby.
Because it's underground, the fire is protected from the DEADLY prairie winds and won't spark a massive wildfire. This design was so effective that the U.S. Military still uses it today for STEALTH operations. But be careful—if you dig this in sandy soil, the entire thing could COLLAPSE, burying your only source of heat.
