The Impossible Fire pit Tornado

I've thought about this project a lot also. It's a tough one to figure out. I've also played with making a desktop fire tornado that uses a candle. Tougher than it sounds.

I've built loads of these over the years and you were really close a few times, but move on from one design to a different one far too quickly. The slatted type will do it, but the gaps need to be tiny (2mm or less) if you're making it that high. The top ring also needs to have a smaller hole to concentrate the exhaust because all the versions you made had far too low backpressure to sustain a tornado effectively. The simplest way to make one is to cut the drum into 4 parts and overlap them in a spiral, and then cap it with a piece that has a hole 1/2 the diameter. If you go up to 8 pieces it can give a tighter tornado effect, but the tolerances are much tighter and the gaps need to be much smaller.

Years ago without that plasma cutter, that project would've taken forever. Great job!

“Number two, they’re 400 bucks for a fire pit. Four hundred dollars for a fire pit. that’s pretty ridiculous, which is why I decided to buy 400 dollars of steel to try to make my own.” this is why I love his channel.

If it's any consolation, fire whirls are incredibly rare and typically last only a few seconds. The fact that you were able to create one at all was impressive.

"California is lit" hits hard for me. my house was burned down in the creek fire and we had to find another place to live. keep in mind that I'd been living in that house my entire life. #MountainStrong

awesome florida man scientist back at it again

With some adjustments, I think the third one you made could have worked. 1) The angle of the fins at the top weren't angled enough. If you compare the angle of those to the angle of the 2nd one you made, it was much less of an angle. 2) You should raise the floor inside it up a little bit so that it's not quite so deep and and put holes in the bottom to allow fresh oxygen in to feed the fire at the bottom. That will get it really hot. 3) put enough wood in and let it burn long enough to really heat up the walls of the stove so that the fresh oxygen coming in at the top fins will be super heated. I think that would do it. I'd like to see you attempt round 2 of this with some of these suggestions, or other suggestions that you have received.

Mark Rober and Science Bob used a ton of fans for making a really cool fire tornado.

Does anyone else get nervous when Kevin starts playing with fire? I keep thinking today's the day he catches himself on fire.
