Boy that’s One Committed Bee!

PotatoesFall, to science_memes in Those were the days!

Explanation? Are these guys huffing ether or something?

Quereller,

They pipette by mouth, which is not very safe.

stolid_agnostic,

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.

They are using their mouths to suck liquids into pipettes. It was an old and dangerous lab technique.

mexicancartel,

Then how are we supposed to do that?

Use a rubber bulb on the end of the pipette. That way your cartel members lab techs are safe.

mexicancartel,

We still use mouth in secondary school. I guess its same in undergraduate degree too. But yeah we only take the base in acid-base titration in pipette

Jesus Christ. 20 years ago my chem teacher used to tell me about the bad old days of having to do this, that it’s still happening today is horrifying.

definitely not standard procedure here in the US. And basic solutions can be more dangerous than acids.

mexicancartel,

I guess they only gjve non toxic bases for school

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 www.integra-biosciences.com/…/pipetboy-acu-2

mindbleach,

That’s the worst squirtgun ever.

funkless_eck,

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

HonkTonkWoman,

Aww, I thought they were blowing bubbles. Looked like fun.

Nice to see me not being the one to post it.

Too many people still think she was french, let´s change that.

In Finnish language we already have the kinda rare expression "rapakon takana" ("behind the mud puddle") about stuff that's happening in America.

ASeriesOfPoorChoices,

Both the UK and the USA refer to it as “the pond”. As in “across the pond”.

I like the cut version better. What do you guys think?

Yep the bottom half absolutely adds nothing to the joke.

It might as well be a reaction video with a side by side of people who “get the joke” and people who don’t. Like, I don’t need a reaction of the person that doesn’t get the joke lmao
