yeah i hated my teacher, he was 26, first year teaching, absolute nerd who couldn't explain anything simply, which was frustrating, i barely passed with a B, and for me, an A student, that's horrible.
but my lab partner(his name was Chaz, isn't that an awesome name!?) accidentally soaked the outside of a test tube with NaOH(have you learned about that yet? its a type of lye that dissolves stuff, an extreme base. at first your fingers feel really smooth and soft but then when the pain kicks in...) and he said it was water but then when all our fingers started to feel funny... lol its funny now but i was always scared of touching anything with him around after that.
