Chemistry!

I've officially decided that chemistry labs drive me crazy. Today I was teaching an Organic chemistry lab and guess what! It was nuts. I had brought some homework to do because I thought it was going to be an easy lab and I envisioned getting my students started and then sitting at one of the benches and studying for tomorrow's exam with half an ear in their direction. Oh my, not to be!
It started with the equipment. The person in charge of preparing for the lab had forgotten and I had to hunt around and find all my own chemicals and equipment. (Thankfully my friend Scott was around and helped me). Then when I tried to give my lecture the class in the other room kept coming in and out and banging the door open and I had to shout to be heard. Then we set up vacuum distillation systems and NO ONE could get vacuum. I fiddled and fussed with all the glassware and rubber hoses and the mercury filled manometers and finally after about an hour we got some suction. Two of them were permanently not working.
I went to help a student and their water cooling system exploded, all over my face and clothes and their lab books and.... everything. Twice, it exploded. Finally I pointed out to them a roll of adhesive wax paper and told them to wrap every single connection in it before they turned it on again.
Four students had heating systems that weren't working. Three students couldn't get their product to distill at all and I finally kicked them out of lab at 5:30 because I had to go home. Two students were trying to get in the instrument room downstairs but it was locked and they didn't have the key and the instrument was in use anyway.... someone else spilled toluene everywhere and it started to smoke. Someone else forgot to put grease on all their glass joints and a glass stopper got stuck in a flask. How do you unstick stuck stoppers? We finally had to break it to get it open.
So I think I must be crazy to be studying and teaching chemistry. I should have stuck with French. French grammar doesn't chip your nails and wash all the nailpolish off. French nouns don't make you reek of naphthalene so badly that my brother tells me I smell like a chemical factory. French verbs don't make my hair go gray and my sanity slip away.
I hope I don't go permanently insane. One day is enough.

Too bad you didn't have a good lab session but in the end, French isn't nearly as cool as Chemistry.

You get glass stoppers unstuck by putting the glassware upside down in a freezer or over. The glass contracts or expands the stopper falls out. (If an oven doesn't work, try a freezer... depends on whether the flask or stopper is better at expanding or contracting)

Anyway, I've never heard of a French bomb. In fact, I've never heard of a French Military Victory, either...
