I'm all fairness to OP, this was posted to boycott US.

I think they're commenting that the sidewalk is super skinny. I legit didn't see it at first glance.

If you'd like to show me how to do, I'll gladly watch that video. I'd recommend a vintage gasoline from the late 2000s, diesel if you're nasty.

I unfortunately tried this as a teen. Didn't work, and you would have to breathe in the entire tube of vapor before you can expect to get any liquid out. Was instantly nauseous and had a headache for a few days. Everytime I see an actor do this I get pretty triggered. What a strange trope.

For more context, that link is a YouTube video by Rollie Williams of climate town (YouTube) and host of the Climate Deniers Playbook podcast.

He's a comedian with a masters in Climate Science. His content is great with quirky editing. Couldn't recommend him more.
