It’s only been relatively recently that people in labs stopped sucking cancer causing and poisonous chemicals out of containers with their mouths on a pipette.
Bulb pipette (like a turkey baster) and glass pipette (like putting your finger over a straw) have been around since the 1940s? Mouth pipetting was banned in most places in the 1970s.

Oh, so this is why they are so insistent in lab that people don’t use a pipette with their mouths. I thought it was mostly a meme!
No, mouth pipetting is a real thing
How do you know it’s done if you can’t get a taste?

Yes, I did say relatively. Although I did hear second hand that was seen by a foreign guest researcher at a facility I worked at about a decade ago.
