Excellent advice on not being afraid of the fire. Leaves are tough. And the smoke cloud was absolutely amazing, David West Breathes Fire 🔥🔥 lol great job
The smoke looked more like a scene from an old Cheech & Chong movie. I binge watched quite a few of your fire roll playlist. Needed to fire up the Big Green Egg so good time to give it a try. One cotton ball & two ignition’s, just need to wait for the burgers now. I can see how playing with this is a little addictive 🔥🇨🇦
Whole-heartily agree with your synopsis of the eddy effect of the smoke. You were right about the pressure differentials, which would quickly vary in relation to ambient air movement and blockage. Back when I was flying hang gliders, we were keenly aware of the "rotor" or eddy effects down wind of wind cresting peaks. I've seen many strange and wonderful sights in the low clouds and fog along mountaintops.
Advanced for several reasons 1) You have to be skilled in solar ignition techniques. 2) You have to understand the coal extending properties of leaves and tinders in general. 3) You must overcome you're fear of fire because you're building a large ember in your fist that will be going to flames... and 4) You must have unusual patience while building and nurturing embers and flames. This can take several minutes for each. Discussion of the "face full of smoke" scene at 6:40. I think this effect was caused by smoke stuck in the negative air pressure in front of my face and then it got drawn towards my face by a backdraft... My head is blocking the brisk breeze that's blowing from behind creating an eddy of air... a negative pressure. As I pull my head back away from the cloud of smoke, I create draft which is pulling a huge amount of smoke towards my head. WHAT DO YOU THINK IS THE REASON FOR THIS EFFECT?

At 6.40 David, you surrounded yourself with a very effective mosquito barrier indeed. As you correctly stated, your body caused a low pressure eddy in the air pressure near you, and as the smoke was following the path of least resistance, (air pressure), you became a smoke magnet. 👍
Hello , Fresnel lens has always been in my all my packs and wallet and day bag. Super light easy to put anywhere. A back up to a back up . So many easier ways to go poof. I dissuade anyone from using leaves . for anything fire. Grass is just as easy to find and no struggle. Leaves would seem like a great fire starter , but it's actually one of the worst and most disappointing. Of all fire tinder. Had to mow the acreage today in Bedford and with the index it was 105 . Long cold , did I mention long winter ? Betcha we have a scorching summer. Every time we have a long drawn out winter , we have a hellish hot summer , I'd bet the milk cow on it , and my kids love milk . Peace.
Very detailed explanations of each step! Marvelous! When it happened my first thought was it's due to the negative air pressure around your head. The same reason smoke follows you around a camp fire. Have you ever done fresnel lense on fat wood? Is that even possible? If you've done a video on that, sorry, but I guess I missed it somehow. Thank you!
Bernoulli’s principle is a theory about fluid dynamics. This simply means that it describes a way that a fluid (a liquid or a gas) moves. When a force acts over an area, it is called pressure. A high pressure will push fluid towards a lower pressure. If a fluid changes speed, it will be matched by a change in pressure. In one sentence: Bernoulli’s principle says that as the speed of a fluid increases, pressure decreases.
Wikipedia excerpt... Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries some angular and linear momentum, energy, and mass, with it.
This is an example of drafting... During a race, drivers can get a speed boost by lining up their racecars. This is a formation called drafting. When cars draft, the leading car blocks the movement of air, creating low pressure behind it. The low-pressure air creates a vacuum, tugging the trailing car forward while reducing the leading car's drag.
