Why does smoke from a soldering iron ALWAYS go towards your face???

Today I've finally answered a question that's bothered me for a long time - if you've ever used a soldering iron, it FEELS like the smoke is ALWAYS blowing directly towards your face, but for years I wrote it off as confirmation bias. It's not. There's a real physical reason the smoke is funneled annoyingly towards your eyeballs, and in this video, aided by a plane laser and a smoke machine, I figure it out!
CORRECTIONS:
1: Safety! Turns out mineral oil smoke CAN be toxic and produce Lipoid Pneumonia, thanks to Cheetah Spottycat below for pointing this out. I chose it initially because the internet told me it wouldn't leave residue all over my garage, but I cannot endorse it as a try-this-at-home technique!

As a guy with stage technician experience, I can tell you: Yes, evaporated baby oil is in fact harmful to your lungs, and can cause what is called Lipoid Pneumonia. If you want to be safe, use regular fogger fluid, which is a mixture of water and propylene glycol or glycerin, which is perfectly safe and won't hurt your lungs. (And why the hell does this channel have so few subsribers ... it's awesome!)

@Scrogan 4 жыл бұрын

So, what’s actually safe about fogger/vape fluid? It still accumulates in your lungs, and it doesn’t evaporate, right? Is it absorbed by your lung tissue and later removed from your bloodstream by the kidney? While for stage smoke you’ll often want it to be buoyant enough to fill a room, but using dry-ice or an ultrasonic exciter should work well enough for this sort of temporary use. Surprised ultrasonic vape pens aren’t more popular. Also I’m pretty sure professional haze machines use oils, not glycol/glycerin, so in small amounts it’s probably acceptable. Though you’d probably get more particulate oil from working with an air compressor than going working at a concert venue.

Glad you liked the video, and wish I knew about the subs lol. I still have fun making stuff xD Thanks for the info about oil smoke!

There are less directions for wind to come from to pick those leaves back up and throw them back into the yard or the street. Its all just pressure mediation.

@ctdieselnut Жыл бұрын

Thank you for this. I tried to think of the answer before I clicked and thought ' it has to be body heat draft'. Seeing cardboard capable of producing the same effect demonstrated it wasn't the body heat, but just the body is enough to produce asymmetric draft. Amazing. This brings up a life lesson I have learned and is constantly reinforced. Just because you can't see how your wrong (in the moment), doesn't mean you are right. The world would be a better place if it was more socially acceptable to change your mind in the face of countering evidence.

I almost always solder at the edge of the table, and smoke still goes into my face if I don’t use a fan. That’s why I’m guessing it’s a combination of these effects or maybe there’s another factor. I’ve noticed that when it’s cold, smoke more aggressively attacks my face, so I think body-heat updraft plays at least some role.

And there was a radio engineering club where we learned how to solder, lay printed circuit boards and make some of the simplest devices from radio elements. There we sat at tables, and everyone had their own equipped workplace, where there was a hood right in front of their hands. I didn't understand why it was positioned in front of my hands and not OVER the place of work, and besides, it wasn't very strong. And now I understand why! And because of this, all the smoke rose straight up and even from me, bypassing the face. The flow was compensated on both sides) The ingenuity of the USSR)))

Next: solve the “drop a piece of tissue paper into the wastebasket and watch it sidestep the basket and land on floor” problem. Some how some way, the problem is air currants. Or maybe raisins. Let me rethink this question.

@bucc5207 2 жыл бұрын

As it falls the tissue pushes a tiny whiff of air ahead of it. The air inside the waste basket has nowhere to go. So the tissue slides off the resulting tiny dome of higher pressure and misses the basket.

How 'bout other mysteries, like why does toast always fall butter side down, or that more ancient riddle, where do the socks go that get lost in the washer or dryer?

@c.l.h.bokhorst6687 2 жыл бұрын

@@TropicalCoder it probably goes butter side down because the butter makes the bread that little bit heavier on one side, and maybe because bread is flat on 2 sides it wants to stand up straight but the side with the butter is heavier. That's my theorie. I never use butter tho, and if I do it's over my plate.

@clonkex 2 жыл бұрын

@@c.l.h.bokhorst6687 The butter's weight would only be relevant if it also significantly affected the aerodynamic forces on the toast. Don't forget that a feather falls at exactly the same speed as a bowling ball in a vacuum. The only reason a feather normally falls really slowly is that it has a large surface area but doesn't have enough weight to push the air out of the way.

Nice… I had pondered this for a long while too, and some years ago tried looking for answers. Hand position was definitely found to be important, so I think we reached a similar conclusion. I also found a difference when wearing a ground strap, so I believe whether you are carrying a static charge contributes too, but I didn’t investigate the point much. What I failed to do was find a universal solution unless you’re happy to use a fume extractor (too much noise for me), so as with most, I just hold my breath.

That tiny slice of laser path cross section is really interesting... 3:10 - This is freaking hilarious lmaoo. I always thought the soldering smoke is coming towards my face because I'm breathing in air. This is why I have a huge exhaust system which sucks out the air from my room now.
