Chem 1 lab, freshman year, fall quarter:
We had all been forewarned by our general chemistry instructor and TA that the burets we were using were VERY expensive. If we were to break anything, we would have to pay for it. The burets were between 60 and 70 dollars. When they told us that, I was like.. yeah whatever I'm not going to break it, I'm not clumsy. Well, I had brought in my cd player and was listening to some music while titrating (yeah, stupid.. I can't believe how nonsocial I was that year). I blame the following event on the ghetto clamps that we were using to hold the burets up over our solution: It was getting to be the end of the period (after a ton of work had been done) when I clamped my buret (which, incidentally was full of potassium permanganate). I somehow knocked the clamp which knocked the buret off which caused the buret to ever so slowly fall to the lab table. It seemed like forever before it hit the table and rolled onto the ground, splashing me and a few students standing next to me, including this HOT chick that I had been talking to earlier. It also knocked my solution over (that I had been titrating) and it spilled all over the table and onto the floor. RUINING everything.. Everyone looked at me like -ohhh you gotta pay now buddy... LOSER (That's what I wouuld have been thinking anyways, if I was them).
Well, I hadn't been doing all that well on the quizzes and tests, and was feeling pretty low already. I had a ton of units that quarter (you guys know, pumped up to do well in college). So yeah.. everything just piled on right then, and I knew that I would get a zero on my lab for the day (which were weighted pretty heavily), AND had to pay 70 bucks for some stupid, clumsy accident that I caused. Everything just went wrong in that class, and I ended up having to drop with a W. However, I still know the hot chick and even though I made a fool out of myself, I ended up tutoring her in chem 2 a year later (after she flunked out of Chem 1) =) It all worked out!! To this day students from that class still bring it up..
I have a few other low stories, this is the one that came to mind..
