Basically it took many years before someone developed something that could be run with a trigger or button. Before that you used a vacuum (your mouth) to pull liquid into a pipette. Heard an older chemistry professor talk about a colleague who years before swallowed a salmonella sample by accident. A lot of people surely got hurt this way.
Explanation? Are these guys huffing ether or something?
They pipette by mouth, which is not very safe.
not a scientist but I’m guessing they are siphoning some chemical by sucking up a small amount in the tube to transfer it to another container
Aww, I thought they were blowing bubbles. Looked like fun.

They are using their mouths to suck liquids into pipettes. It was an old and dangerous lab technique.
Then how are we supposed to do that?
I am a bit concerned everyone is just mentioning the squeeze rubber ball thing, maybe because its time appropriate for the images.
But in modern times people should use something like this https://www.integra-biosciences.com/global/en/pipette-controllers/pipetboy-acu-2
That’s the worst squirtgun ever.
