went to mad jack's for dinner with xwt. haven seen her in eons too. we finally met up. =)
let me ask you a question. you have 2 beakers, beaker A and beaker B. both were filled with tap water, both had 5 nails each and both had a lid to cover the beaker, ceteris perabus. *haha* but you boil the water in beaker A. after 5 days, you realise you forgot to label the beakers. so how will you know which beaker is beaker A?

Ans : the nails that did not rust in the beaker is beaker A.
if you knew the ans, good for you. but silly me told a student that the nails that rusted belonged to beaker A. well, you can't blame me for giving the wrong ans because i haven't touch chem for like 2 yrs+++. whaha! luckily it was just one student. aniwae, when i flipped through the papers of those who handed in, they gave the ans i thought of without me even telling them the ans. haha. self-comforting. LOL
