You went way further in Chemistry than I did. My main memories are of my teacher letting me make thermite and nitrocellulose as extra credit projects. These days that would probably get you a visit from DHS.
My worst project was extracting Lysergic Amides (same basic structure as LSD, without a couple of groups hanging off) from Morning Glory seeds........, which would have gotten me a visit from the law back then, as well. I went thru about 4 exctractions to see how "pure" I could get it, and then did a final extraction into ETOH (distilled straight grain alcohol). I didn't stop to think and realize this meant it got absorbed directly thru the mucous membranes in my mouth, thinking I had about 45 minutes like a "normal" hit of acid. I took almost 500 mics which is a WHOPPER of a dose, and I was tripping my eyes out almost immediately. By the time I walked out of the lab, I didn't know where I was. I wandered around campus for almost 4 hours smiling like an idiot, till my roomate happened by and saw me staring intently a the trees "weaving patterns." He took me home and kept me from anything more outrageous.
This year in Gen. Chem--I've done titration of hard water, diluted NaOH, and synthesized alum.

Definitely. Though the only complaints we got were from annoyed teachers that had to listen to the loud thuds from people lighting their black powder in the fume hood.
