ramblings of 03S78

03S78. HCJC.

27 of us make up the lovely class of 03S78 :)

it was a year and 6 mths ago that we graduated from hwachong, nothing much has
changed since then - we still have the good old class outings when we spend most
of the time walking around (+ extended one in europe recently), we still play
mahjong, watch movies, go æçå¦! together (at nwxiang's request of course)..

to many more years of friendship!

chem lects..

..are so fun =)

our chem lecturer did a demonstration in front of the LT today.. we were learning about molecular orbitals (MOs).. so according to the theory, nitrogen is diamagnetic (not influenced by magnetic fields) but oxygen is paramagnetic (attracted to magnets) cos oxygen has two unpaired electrons in the 2p* MO (dun worry if u dunno wad it is.. neither do i =P)..

so he whipped out two innocent-looking thermos flasks.. the first one contained liquid nitrogen (!), and then he proceeded to pour that into a test tube suspended in air like a pendulum.. one thing weird was that he wore a labcoat and safety goggles, but he din wear any gloves.. he was basically pouring liquid nitrogen with his bare hands! anyway he then brought an "insanely powerful magnet", to quote him, and then brought it close to the test tube.. then he said, "look at the test tube closely.. u're not supposed to see anything.." everyone was lamed out at that time cos we didn't noe nitrogen was diamagnetic, so basically everyone was craning their necks to look at.. nothing -.-" the cool thing was that he "cleaned" the test tube simply by pouring the contents out.. and for good measure he splashed some of the liquid nitrogen from the thermos flask on the floor.. everything evaporated within seconds, but the sight of it was pretty cool!

then, he proceeded to fill the test tube with liquid oxygen, and he brought the magnet close to it.. and lo and behold, the test tube was actually attracted, and it stuck to the magnet! it was sooo cool!!

to cap the demonstration off, he poured liquid oxygen into a metal pan containing rice crispies, and set it alight.. the entire thing burned merrily for a few seconds.. and he admitted the demonstration was a good way for him to play with liquid oxygen.. erps.

everyone gave him a big hand after the demo cos it was sooo nice! sigh i should have done similar stuff when i was teaching.. i think any student would love a good sight of things being set alight, wouldn't they?
