My freshman General Chem lab was a total disaster most days. One day stands out in particular. My group of friends in that lab had gotten the reputation of being the last to understand stuff, bugged the teacher with the most questions and were always the last ones out of the lab. We called ourselves the “speds” (special ed kids). This one day it was the end of class and we were supposed to finish up our experiments and clean up…our professor stepped out for a few minutes. One of my lab partners was quickly trying to heat a test tube over the Bunsen burner and it exploded on her, and another lab partner got startled by the sound and dropped the teachers stapler, which he had been holding, into a vat of waste chemicals. Meanwhile I had walked over to the sink to dump out my test tube, not realizing that the waste product was supposed to be collected into a separate container, and when it hit the water in the bottom of the sink it created this purple smoke cloud. I was panicking not knowing if I had just created some toxic gas. (I don't remember what experiment we were working on) All this happened pretty much simultaneously, and our professor waked back into the room right in the middle of it. He just gave us this priceless look that told us he though we would all have bright futures as Wal-Mart greeters. Luckily we survived all those years of chem labs and our many other screw-ups, and now one of us is a science teacher, one is a physical therapist and I am the assistant manager of a toxicity lab. - arikool, on 05/13/2008, -0/+0האם חוק ה- Buoyancy מתייחס ל-חוק הציפה על המים, או ל-חוק שמחת החיים ? עדיין תעלומה. מי יסייע ?
