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!
