Top best answers to the question «How does a fire tornado experiment work»
The vertically rising hot air molecules collide with the rotating screen, and the angular momentum of the screen is transferred to the rapidly rising air molecules, giving them a “twist.” Fresh air fuels the fire from the bottom, and the flames twist into the shape of a tornado.

How Does It Work. As you noticed, simply spinning the tray does not whip the fire into a twirling tornado. It’s only when you center the fire in the middle of the rotating screen that you create the perfect fire tornado. It all starts with the heat from the flame that causes the surrounding molecules of air to rise.
Fire tornadoes, however, aren't formed by conditions high in the atmosphere; they're created by hot, dry air rising rapidly from the ground. In that sense, firenadoes have more in common with...
As the hot air floats upwards cold air moves in from the sides. If you add a mesh around the fire and spin it, then the air coming in is forced to spin slowly. Hot air rises above the fire, drawing in cold air from the sides. If the air has to move in through a spinning mesh then it is also forced to rotate.

How Fire Tornadoes Work. A fire tornado veers close to homes during the Freeway Complex fire on Nov. 15, 2008, in Yorba Linda, Calif. Strong Santa Ana winds helped the fire to destroy more than 30,000 acres and 314 residences. A tornado just might be nature's greatest spectacle. A small one inspires awe and wonder.
Light your fire and turn on your fans. Go around your circle and adjust the fans as necessary. Tips: Turning the fans on too strong of a setting can kill the fire tornado. Try weaker settings first. The angle of the fans should be barely off center. Turning them too far will kill the fire tornado. Safety Note: do not throw anything into the fire container. Your fuel will splash out and spread fire.

As it does, the column of air will whirl, or rotate around a vertical axis, much like water draining from a basin. They become visible when they pick up debris from the ground and are often named to reflect the nature of that debris: dust whirls (or dust devils), sand whirls, snow whirls, even hay whirls. Fire tornadoes develop when a blaze ...
