What's the biggest screw up you've ever done in a lab or seen someone do?
>>
>>8584517
I farted so hard that the professor and all students needed to leave for a couple of seconds (I was the lab technician)

my biggest screw up isn't all that dramatic. for O-chem lab we were extracting limonene from citrus peels (lab smelled FANTASTIC as a result) which meant keeping an acid solution containing the peels at reflux. I leaned in to read the thermometer (fume hood door was fairly high) just as a big bloop of vapor came up through the condenser, and I got a dilute puff of HCl in the face. my nasal passages felt a little raw for a few days but that was it, since I was wearing my safety goggles.
>>
>>8584517
i once touched a diffraction grating with my finger. five years since that happened my fingerprint is still on there and no one knows that it was mine.
>>
>>8584591
>to read the thermometer
Liar, you went to smell the vapour and forgot to waft (like a pro). Though, to be fair, the same thing happened to me when I was cooking meth, so...
>>
Well since I'm a computer science major I've only had to do one class that's involved a lab and that was chemistry. My partner was a milf and she thought I was really cute and I had her do all the work and I pretended to try and let me tell you I was a god damn expert at pretending to contribute on that shit. Felt good getting an A in all my labs without effort. I miss that woman, really wanted to fuck her she was sexy she had a slim body and a nice petite ass with a freckle face. But she was a reserved person who had a boyfriend so I wasn't going to put myself in that situation. I sure do miss her. Oh but to answer your question I made zero mistakes since again she did all my work for me.
>>
>>8584609
the thermometer was inside a condenser. the condenser was all fogged up.
believe me, the whole ROOM smelled like oranges. there was no need to lean in to sniff.
>>
>>8584667
Sounds like olfactory heaven, anon.

>>8584517
Charred $450 worth of organic product and 3 mo of work. It still haunts me to this day. Although its not the worst I've heard.

A prof told me a story that when he was an undergrad, first day during the meeting he and the PI listened to a 2nd yr grad student say she was having trouble with a reaction for 6 months. Turns out she was trying to do something that was literally impossible. The PI said "once I get some fucking grant money it'll only be undergrads and postdocs because postdocs know what they're doing and undergrads know they don't know shit!"

This one time I accidentally unplugged this freezer.

Honestly I would rather not talk about it again..

Anyone who takes the time out of their day to write a paragraph fetishising their lab partner, then goes out of their way to provide an explanation as to why they didn't pursue said lab partner (to a bunch of internet autismos on /sci/, no less) just has to be either a virgin, or a pathetic person with too much time on their hands.
>>
>>8585064
You're a virgin because you post on this board.

I'm not even the guy you're replying to
>>
>>8585064
I don't even think there was a lab partner. He's just a talented story-teller.

On-topic, I just learned about the demon core.

Not my story, but a lab mate was telling me a story about what happened at a biotech place he works at.

Long story short, someone fucked up the buffer stock and about $500k worth of protein had to be poured down the drain because of it.

i was a TA in genetics lab and accidentally put the wrong primers and sequences out in lab for my 2 sessions for a PCR and electrophoresis

No one received results and no one isolated gene sequences from my screw up, I found my error after multiple students complained that their shit was bandless and some students stayed over to repeat their study and it still came bandless

>tfw accidently grabbed glucose solution droppers instead
>tfw I only took undergrad genetics and was a graduate biochem student
>>
>>8584517
Not that big of a screw-up, but I was on the bus heading to the Chemistry practical exam, and I was talking to my mates, one friend tells me
>I'm so stressed, I double-checked if I took my labcoat this morning
>Haha, that's funny
>Wait

And that's how I almost got an F to this test.
>>
I once caused a small flourine fire.

The sheer panic I felt....you ever seen concrete on fire? Would have been beautiful if the fumes weren't life-ending poison.

I got it out and manged to cover the whole thing up. Thank God I was working outside and none of that shit got on me. Never again will i fuck with anything that nasty.
>>
>>8584591
Same exact thing happened to me in my O chem lab last summer. Loved the smell of the lab
>>
I was quenching about 10 g of LiAlH4 in a litre of ether, by running dilute sulfuric acid down the side of the flask into the solution.

There was a bit of dried residue and for a few moments I got to see some glowing embers where the dry LiAlH4 was reacting with the water.

>>8585332

You were working with actual gaseous fluorine? Or some other fluorinating reagent?
>>
>>8585064
>The stories and information posted here are artistic works of fiction and falsehood.
Only a fool would take anything posted here as fact.
>>
I heard a story that happened in my lab a few years ago.
Basically there is a research group which works on advanced fluorescence techniques, and had among other equipment a state-of-the-art STORM (stochastic optical reconstruction microscope) setup, which was really expensive, with lots of table optics elements and so on.
One day, someone from another group decided to wash glassware using aqua regalia. He put like 10 liters of the acidic mixture under a fume hood and let it boil to clean stuff. The thing is that the fume hood was not working, and was also connected to the microscope room where the STORM was. When people went in the room to use the microscope, everything was destroyed, including the optic table (!).
Basically a microscope setup worth 500k-1M was ruined, and they lost like two years of research since they had to assemble a new one.

My o-lab always reeked of acetone, i actually got nasues once or twice every lab and woulf take a break in the bathroom

Pro tip: she was aware you did nothing and would have felt bad if she mentioned how useless you were. In fact she probably ranted to her bf about how shitty her lab partner was and how she does all the work. I've been in that situation before (minus,the qt bf)
>>
I used the wrong pipette and contaminated one of the stocks for the entire Orgo lab. I was the first one to get the solution, so everyone else after me ended up getting no reaction, and yet they never found out who contaminated the stock.
>>
>>8584831
Oh come on it can't be that bad, aren't freezers insulated anyway? Did you like ruin a lot of rare samples or something? Surely they would have freezers like this with a dedicated un-unpluggable electrical supply, so i doubt a freshmans could fuck it up
>>
>>8584831
Oh man! tell us again!
>>
>>8584517
Nothing too major.

Dumped 8000 psi of air into a 2000 psi max pressure gauge because I grabbed the wrong dial. Tooted like a train whistle and fucked all the mechanisms up. $500 to replace.

Also I put a tray of rock plugs into the 100C oven instead of the 60C humidity oven, which dehydrated them and collapsed the clays, fucking the porosity.

Mining lab, btw.
>>
I leaned on the emergency power switch and delayed an experiment by an hour. Not a big deal honestly.
>>

Chlorosulfuric acid

Never again
>>
>>8585423
I could buy the fume hood not working, but to have it vent into another room in the lab? Bullshit.
>>
>>8585775

All the hoods would be connected to the same extract system, so if the whole system was down then vapours from one hood would diffuse into the ducts and down everywhere else, presumably.

Depends what the timescale was.

Physicists and chemicals seem to be a bad combination, I've heard of one lab where they needed to clean a lot of silicon wafers for surface functionalisation, so somebody decided to make up a nice big bottle of pirahna solution and then tightly stopper it and keep it for storage...
>>
>>8584556
One time one my professors farted when he was going to lean forward to help us out.
>>
>>8585775
>>8585823
It was an old building, and the fume hoods were connected in some way, idk.
Anyway, the story is not bullshit and it severely held back the progress of the lab at an important moment.
Feel free to call bullshit, idgaf, just telling what I heard from the head of the group
>>
>>8584597
This is evil
>>
I was in a lab with a guy who was one or two steps away from creating dimethylmercury. Without a fume hood or gloves.

Professor nearly had an aneurysm when he realized how close we came to all dying in the shittiest way possible. Never saw that guy again, I think the Professor managed to get him expelled.

Don't take it personally, we just get a lot of people making up shit in these threads. Usually more fake shit than real.

Good point about connected ducts though.

You sure you don't mean diethyl ether? Never heard of people getting dizzy from acetone.

In secondary school when we were creating hydrogen gas with hydrochloric acid and some metal, one hurr durr gurl took burning match and put it directly in front of pipe where gas was coming from. Erlenmeyer exploded and acid flew all over the class room. Fortunately we had safety glasses
>>
Someone put plastic in the glass waste bin

So every single student in that Chem quad got 10pts taken off their grade

Wasn't our section though. I had to put something in the bin at the end of class and there wasn't any plastic in it then

This is a story my dad always tells me about when he was in grad school.

Two grad students were fighting about whether a brick of sodium would float or sink in water. The one remembered his high school chemistry demonstration showing that a small chunk of sodium clearly floated. The other remarked, "These are merely surface effects, like how spiders can use their hairs to float on water" and that they were "unable to scale properly" to a scale of a brick. The brick of sodium would sink, as the molecular weight of sodium is greater than water.
Like good scientists they decided to test this hypothesis. They carefully measured out a kilogram of sodium from the store room, brought it to the school lake, and threw it in.

Well, they found out that sodium does in fact float. The surface of the sodium rapidly oxidized, releasing heat, hydrogen gas, which instantly ignited, creating an almost-hovercraft ballooned up by burning hydrogen. The brick raced across the lake and into a group of neighboring pine trees, which of course ignited. The grad students called the fire department, but never let them know the source of the fire.
>>
Took a chem gen ed at the end of high school.
Our project was making fireworks because we were in a private school.
My buddy put too many chemicals in his mixture which apparently brought the ignition temperature down below the temperature of the corning oven.
It lit everyone's fireworks and almost burned the school down. Fire department came and yelled at our instructor. Had a good giggle.
>>
I once needed to mix Nitric acid with ethanol, I didn't knew that I need to dilute first. That shit started to turn green. Just ran out and watched that eruption for some seconds, and then I cleared all. The End.

In a high school chemistry class I once opened the super concentrated lab stock solution of ammonia and took a big sniff because i had read in my textbook it had a strong odour.

Fucking almost knocked me out. I lay down on the floor and had tears streaming out my eyes for hours, lungs were on fire.

Good times

my dad's an ME and he told me an amusing story from work.
the company he works for makes a lot of audio equipment. for whatever reason (don't remember what exactly the test was) there are some things they do with prototypes that require a nitrogen atmosphere. so they have a sealed chamber to run tests in.
one time, management brass comes down to see what those pesky engineers are up to, and is super excited to see the test in action. when they're ready to open up the chamber afterwards and remove the prototype, they tell him to stand back from the door. he doesn't listen...and promptly faints as the pure N2 washes over him.

What would happen if you threw it onto an ice cold lake? Would the temperature be low enough to keep it from auto-igniting?

Also, shouldn't it have exploded like the one in this video?

True story

Not a lab story and not mine, but a freshman in my uni thought that nobody would notice if he took an expensive-ass anatomic model home to study

Head of anatomy dept went ballistic and decided that nobody would pass anatomy until the model appeared.

That year there was an historic low in the anatomy pass rates at exactly 0%.

I accidentally used LB medium with antibiotics in them, than without. Mistakes were made. Needles to say, nothing was growing after that. (I had to grow some E. coli for plasmid extraction etc.) It was bad, because it affected the schedule.
Also once when I was extracting plasmid, I forgot ONE STEP (rinsing plasmid colum for 2 minutes in centrifuge, at the very end). And when I wanted to see concentrations of plasmids, they were shit. I was so pissed to myself and stayed at lab until 9 PM, so I could do everything all again. End of the day, plasmid extraction succeeded, with "ok" concentration. Not really that big screw ups, but something i guess.

Start with 8th grade high school, generic science class but it was a chemistry lab and we were making bleach with sodium hypochlorite and somebody got something mixed up and suddenly we had to evacuate the entire school because somebody made chlorine gas

In 3rd year Mech Eng. electrotechnics lab somebody tried to "fix" a very large and expensive power supply, unfortunately I wasn't looking but when all was said and done the power supply was completely destroyed and somebody had to take a trip to the hospital because of electric shock.

I took a graphic design class for my free elective in fourth year to get an easy high distinction and watched as a gaggle of art students took apart an old cathode TV and almost killed themselves on the capacitor before I showed them it was still holding a super fucking large charge, the lab tech almost had an aneurysm on the spot when I told him what they were doing

I have some from robotics lab.

We took about 2 years to build a quadcopter from scratch only to throw it to the wayside and buy one pre-built (which was soon after driven into a wall and destroyed).

One of our methods our group called "dynamic tethering", which really consisted of a lab member holding the copter while feeling the force from the motors to tune the PID controller.
You can tell which members were part of the quadcopter group, because they had slashes all down their arms from the blades.
We have a nice set of safety goggles with a slash across them, which a member was wearing (safety first)

>>8595946
Another robot, called Fenrir, is usually called in the papers I found as a pendulum bot. It consists of two large (3 feet iirc) wheels with a counterweight offset from the center (250 lbs?)
I mention the name, because its named after the norse god (norse beast) called Fenrir, that killed Odin (a robot we competed against).

Instead, Fenrir preferred the blood of children and computers.
Fenrir had a glitch where on some boots (1 out of 100 or so) the motors would both go full out and chaos would ensue. Once this meant that it drove to a group of children down the hallway, thankfully it crashed into a wall instead. Two other times, this meant it ate a computer. one the labs, another time a personal one.
So how this would happen is that when uploading code to the arduino, we would of course be plugged in via standard usb a-usb b cable. The robot would go full out, pull itself off the stand, and start rotating, slowly pulling the computer to the robot's maw (I think we saved one compputer from this fate).

We later found, that it was a problem with the specific arduino, and replacing it removed the problem

I found out some time ago that gallium is extensively used in semiconductors. I have a friend that works in waste management who could get me shitloads of old computer parts, we're talking heaps 6 feet high of them, so i spent a long summer processing out the gallium and other metals from them. Got a pretty decent chunk of gold out of the whole thing too.

The prank wasn't the primary purpose of the gallium, of course, but i figured why not do it? I just scraped it off of him and recovered the stuff that fell in the grass. i wanted the gallium to find out how it affected different alloys of aluminum and just for the sheer joy of having over a gallon of what i think is the prettiest of all metals in my possession.

funny that i could have made money off of it, but that wasn't my goal at all.

That reminds me of when I was nearly killed by a turbo pump.

These are like jet engines with rotor and stator and lots and lots of blades rotating at GREAT speed, except that the blades are powered by an electromotor.

When these go they shred themselves and throw turbine blades clean through the casing and into whoever is sitting close. i was nearly bisected when the turbopump suddenly ingested a lot more gas than it should.

It is amazing how the mind reacts. Realisation of impending doom took miliseconds, as did the realisation of what to do, followed by throwing the right switches while thinking at the same time how slowly time suddenly passed.

Making polyacrylamide gels, smashed a 100ml bottle of TEMED. Vapor hits you like a slap in the face in that concentration. Had to evacuate the lab and get blowers in to make it habitable again.

In high school physics lab we were playing around with circuits and I connected 6 large batteries in series with each other.

We then left the classroom to do some shit for 20 minutes and came back and one of the batteries had burst all over my partner's notes.

I was the golden boy in the class or however you call it, and I just told the teacher I must have left accidentally a cable that coincidentally touched the other end of the battery

I forgot to add the fucking primers when I was attempting to undertake site-directed mutagenesis. My prof and lab-bros thought it was pretty funny, particularly as I was the guy who usually got DNA concentration an entire order of magnitude higher than they did.

In a similar scenario, someone in my physics 2 class hooked up 6 6V batteries up to a DC motor with a propeller on it

Loosely

Nearly killed someone and a piece of propeller was lodged in the whiteboard
