Shoot. When I was in high school (in the very early 1980s), we made nitroglycerin and nitrogen triiodide as part of chemistry class.
The instructions for making nitroglycerin were in the high school chemistry text book, and it even helpfully explained how to improve the rate of the reaction for faster production.
The guys making nitrogen triiodide were doing so in the enclosed vent chamber, and they sternly warned the instructor not to throw open the door. He failed to heed their warnings, and it exploded and burned off his hair and eyebrows. There were no lectures or discipline -- he acknowledged that they had carefully warned him not to be careless.
What they did with the liquid suspension was rather creative. :) It's basically inert while in suspension, but very unstable when dry. So they took eye droppers and wandered the halls of the school, randomly dropping drops of it on the floor. It dried in time for classes to swich. Lots of little firecracker bangs as people walked down the hallway and activated the dried samples on the floor. :)
As a junior high student (and high school student), I used to go around the school demonstrating potassium permanganate and glycerin for various classes. It was a great way to get young minds interested in the sciences and fascinated with chemistry.
Now, all 4 of my children have had high school chemistry (youngest is just now finishing it up). There is NO experimentation or lab work -- they are not allowed to touch any chemicals. The teacher is not even allowed to do the potassium permanganate experiment -- it is deemed too likely to cause students to become terrorists. I'm thoroughly disgusted by what has happened to the educational process in this country.
My oldest is graduating college in 2 days. Over the last 4 years, he has brought home horror stories about the rigid mindset that he has experienced in the classroom. Nearly all the college instructors (and this is at a large public university) absolutely insist that their perspective be parroted back -- there is zero tolerance for discussion and debate. People with differing beliefs and perceptions are publicly ridiculed and humiliated.
When I was in college at Texas A&M, my philosophy prof was the faculty advisor for the Gay and Lesbian student association. Despite the fact that he and I shared very few common positions on the topics discussed and written about in class, we got along well. He commended me at the end of the class, saying that I had presented my positions with clarity and precision, and I achieved a high A in his class. Apparently, that experience would be rare now.
