That's not why you learn that sort of stuff at school. It's all about getting your brain to work in rational and logical ways.Quote:

little Johny is no more
for what he though was H20
was actually H2SO4"
:laugh4:
What... you hate chemistry... I love it...heheheh....
and you should hate THIS...

The rythm is slightly broken but I really do not think it will be a problem with enough quantity of the latter substance.
Both H2SO4 and C2H5OH is easily distinguishable from H2O... here is the better version from a chemist's prespective... (look your handbook... LOL):laugh4:

Yep, H2O2 (HydrogenPeroxide) is an odorless, colourless, and nearly identical to water, except it was a powerful oxidator that could easily burn your intestines and exploding them...:laugh4:
Oh, it wasn't part of the curriculum. My teacher thought it would be more fun. But then again he would test what colourless solutions were by taste. :dizzy2:Quote:

I took it all the way up until the end of high school for no other reason than the credits. Somehow I managed to get A's. Don't ask why, as I'm not quite sure myself. I hated it.
He's right, sciences are supposed to make you experiment, rationalize, solve problems, and such. Unless you want your school to consist of banging rocks together to try to make fire :juggle2:, I don't think you should really complain. But that's just me.Quote:

at least in biology we dissected cow hearts.
Yeah bio was cool. We dissected some kind of brain (I can't recall right now) senior year.Quote:

ooo and on the last class in bio we dissected a fetal pig. THAT was fun!
