Cooking pan designed to create a columnar vortex of air ("tornado") that sucks up cooking fumes and channels them upwards neatly into an overhead vent. See URL link provided.

But how? What causes such a phenomenon? |

I’m with 21Q on that question but if you can explain how it works I’ll [+]. And if there is a way to make it work, then I’ll be disappointed that I wasted the idea name “popcornado” a few years back because suddenly I have an idea… |

Probably had a bit to do with barometric pressure as well. I suspect things like altitude and weather conditions such as humidity are going to play hugely into your ability to replicate the effect consistently. |

We can have an overhead fan that helps create vortex suction from above. We can also have vortex being caused by the pan below. The pan vortex could result from Coanda Effect by having ridge-fins on the inner circumference of the pot, to encourage air to move in a circular flow path. SEE URL BELOW. We could also use magnetic induction heating, and have the induction effect moving in a circular path around the circumference of the pot. We are trying to tip the air convection into circular vortex motion. |

um... when you make a sudden low pressure region, as in raising a lid off of a heated pan, and give a little twist, then inertia takes over and keeps twisting the rising heated air and wraps it into a tornado if it can. |

Assuming this could be made to work repeatably, it would be a heck of a sight during a grease fire. |
