clicky

I hate you.

I remember the teacher playing that in my Chemistry class

One of my lecturers wanted us to memorise it last year. I still can't do it

It's fun trying though

I remember a poem that my chemistry teacher told us...

"Mr Thickbroom is dead and gone
His face we'll see no more
For what he thought was H2O
Was H2SO4"

That's a big mistake to make.
