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.

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.

Look how long their fancy straws are! I bet they keep chemicals a safe distance away from possible ingestion!
