Fire Tornado

A story of one man's love of a fire tornado demonstration. A small metal container sits in the center of a 13" diameter turntable. Bending and clamping a brass screen (10 wires per inch) around the perimeter of the turntable forms a 36" tall cylinder. Isopropyl alcohol in the small metal container is lit, and the turntable is set in motion.
As the surrounding air is drawn to the flame, it is deflected from the center of the turntable as it passes through the openings in the screen. The resulting angular momentum of the gases helps to form a tall, twisting column of fire.
FIRE IS HOT!

HAHAHAHAHA

[@PlasmaChannel]

Harvard, great video. It appears our two channels have come up with different methods of creating a fire vortex! We too released our fire tornado episode recently.

Great explanation, superb learning experience. Give me more!

[@xofunkox]

Great demonstration...

[@bookdream]

science is beautiful

[@lohphat]

How about adding an impeller at the top so the rising heat turn the unit by itself?

[@NatSciDemos]

Interesting idea.

[@ARCSTREAMS]

use smaller dia mesh cylinder

[@originalmianos]

Why only isopropanol and not maybe ethanol?

[@NatSciDemos]

We only use isopropanol because it's cheap and it makes a nice orange flame.

[@PlasmaChannel]

additionally, we've found other fuels burn with residue, while isopropyl burns very clean

[@THOMASTHESAILOR]

Other fuels smoke like crazy, believe it or not, that fire is starving for more oxygen..

[@pedrononino4223]

Does that increase fuel consumption ?

[@DanielRosenberg]

Yes, it does. The flame is small when the turntable isn't moving. When it turns, the air moves faster at the center, fanning the flame and making it burn faster. Faster burn pulls in more air, which is moving faster. Good question.

@@DanielRosenberg oh nice! this channel is awesome, ive been getting lots and lots of knowledge and ideas to create Interactive Didactic Sound Instruments/Instalations that shows/teaches/uses science experiments and this could be one

[@ARCSTREAMS]

id love to see this with green flame,,just mix boric acid and methanol
