What Does That Smell Like?

Last week on Tuesday, in class, we did a lab. We had to smell vials of different compounds. Some smelled really sweet and nice, but some smelled REALLYREALLYREALLY bad, especially the ones at the end. We did the last few outside and at first I was confused at why we were going outside, but once the lid was opened I understood. I saw the bubble wrap and got excited and once it got lifted I jumped and didn't want to breathe. It was another interesting lab though =P
