Let's light a match. We're watching to see if we see anything floating over the fire. We bring the match to the bottom of the glass and hold it for a while. Before we proceed to the second stage of the experiment, we wait for the glass to cool down.

There was a black mark on the bottom of the glass. You can wipe it with your finger, then you can see the soot on your finger

We need a vacuum cleaner and a cosmetic flake. We go outside with a vacuum cleaner, turn on, clog the pipe with a cosmetic flake. ( of course, we go out as much as we need a cord). We suck in the air for about a minute, look at the cosmetic flake and draw conclusions…
