Tell you what?

They’re likely just bubbling hydrogen into soapy water

well not hydrogen probably as the reaction would be much more violent. I’m guessing this is more like a carbohydrate gas (methane, propane).

This is a very common test in chemistry.

Yup bubble gas of the sort you use to cook with through a tray of soapy water to get the foam (you can see the white tray behind them on the bench). Hydrogen gas would have been a different colour I think.
School labs usually have those gas taps on the benches, and rubber hoses to connect to bunsen burners, just stick the end of that into the soapy water.
Don’t mix air in with the gas though. When it’s just pure gas (methane, propane etc) it’ll burn from the outside inwards so you get a pretty effect as seen. If you mix air with it, the whole lot burns at the same time which we like to call “an explosion”.

It’s definitely methane bubbles, I am a chemistry teacher and I do this demo every year!
