Explanation? Are these guys huffing ether or something?
They pipette by mouth, which is not very safe.
but how are we supposed to accidentally discover artificial sweeteners?
By distilling piss from diabetic people? Idk I'm not a scientist i just like the memes
WTF? Piss is all natural!
unless you drink from the pipet
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.
