Welcome to my blog! Tag as much as you like =D

JUNE HOLS!!! =))

yup, it's finally here! but NO - it does not mean rest time! gah... can u believe it? we have like 7 projects to do this hols, not counting all the homework and other random stuff...so why am i slacking now??? shit.

ok anw, went for ncw treasure hunt at nus today. team of 4 with mr koh, wu and zhao yuan. tried out circle line frm my hse to serangoon (wu's dad fetched us to nus), it's great and fast, but then i still hv to walk quite a long way.

had to reach nus at like 11+ to register. then, we went to watch the fact or fantasy quiz, there were 30+ teams, but RI only sent 3 teams from chem RA. mr ong was there too. quite interesting quiz, but after awhile it got boring. anw, our race started at 1+. round 1 was this crossword puzzle where we were supposed to find at least 20 names of elements among 40 in a crossword puzzle. we took 4 mins but dats because the first 1-2 mins were wasted on getting a pen lols. ok next, for round 2, we went to this lab where we were supposed to do a few experiments and answer questions. this round was real interesting! okay, i think there were around 8 experiments. ksp was a great help but even he got stumped at sum point in time.

i rmber there was elephant's toothpaste but we didn't do it cause there's no point. question was identify the ingredients (H202 and KI). learnt before in school haha.

there was also this solubility and immiscibility thing where you get different coloured layers, different layers with organic solvents and water and one more thing which i forgot, and also solubility of stuff in organic solvents n water, like iodine in organic solvent to be dark purple. but, we had to use chloroform and i spilled a few drops on my skin! shit carcinogenic thing. there was also this acetate salt too but i cant really rmber cause i know i was quite worried after the chloroform spilled de first time and my hands got quite a bit shaky XD even de prof said "your might wan to get someone else to hold the testtube". and i found out that working under a fume hood is actually quite hard, esp when de cover is down. i tink i should try to get used to it, might be doing a lot of it for my scsf proj.

there was also this slime thing with borax, we were supposed to describe the thing formed. actually for this one, initially we described it as "gel" like but then, some professor there hinted that the title of the experiment was a clue. you see, the title was "gooooeeey smile", and smile's an anagram for slime. but after that, the professor said that "gel" was de better scientific answer compared to the layman term of "slime". haha with mr koh, obv got better scientific answer lol. mr koh was of great help actually, i think we relied on him a lot, not jus in de chem part, but also coz he's de only one who knows de way arnd nus XD

nxt experiment was identify an unknown solution (which was actually quite easy - its potassium permaganate), actually de experiment is just QA with ppt of sulphur from sodium thiosulphate and redox with KMNO4 as the OA. wasted sum time there initially though, because the description of the experiment was wrong.

nxt one, we did this filtration of chilli, and the filtrate we added KI, and we got a YELLOW PPT. shocked?? yep chilli has lead, can u believe all this while when you were eating your french fries with chilli, you're actually consuming lead?? lol ok luckily, after we clarified with de prof, he said that chilli in singapore doesnt hv lead, so dun worry =)

this experiment was COOL! oscillating reaction. solution with hydrogen peroxide, sum iodate, sulfuric acid, sum manganese salt and i tink malonic acid. jus go search oscillating reaction in youtube or something, you'll know what we saw. i took a video too, but i wont post it yet until i get de photos which zhao yuan took today. anw yea, so basically the solution keeps changing colour on its own, and its damn nice. why can't we do this kind of reaction in school as demos haiz... we'll be alot more interested dur classes

i can't rmber the rest of de expts.. mayb i'll update when i remember..
round 3 was actually quite easy, though i tink we screwed it up. just go get a picture of this long crystal, go to a statue on 'waves and particles' and say what chem theory it reminds us of, and lastly, go to a poster and identify and copy de structure of a molecule shown on de poster. this was where we SCREWED UP. we looked at the wrong thing and thought it was methane, when actually it was supposed to be the WATER molecule on the ncw poster. stupid. okay, that's the end of rounds 1-3, will be doing rounds 4-5 in de nxt few days. but rounds 1-3 were FUN. very very fun. great chance to work with mr koh, wu and zhao yuan. really enjoyed myself =D

so we ended quite early actually cause we were running everywhere dur de hunt. im serious.. running. din't manage to take video of mr koh running XD but he was always at the front. u'll laugh like sum mad pig when you see him running =P slacked awhile at some place (i dont know my way round in nus) with aircon, and we chatted for awhile. and we finally decided to go partyworld ktv at clementi. quite ex though for today, since it's weekend. but still, its only once in a while. and i had a GREAT time singing with wu, mr koh and zhao yuan! fun and destressing XD

and before i end, i tink nus is really more rundown than i expected. and nus is super dangerous lols. but thats only when you cant go through a place because its locked, but that happens quite often, so well... anw we had to cross certain places by going the AIRCON WAY... aircon way as in walk on dangerous ledges with the aircon things on it and i'm serious. its like nus become an obs site or something. yea and you'll be without a harness. o and we saw these ppl doin this cool experiment. using water to start fires. they were testing diff mixtures of metals? i dunno, dey said they couldn't reveal. anw, then one guy would spit water at the mixture and de metals get ignited. quite amazing.

today's been an eye-opening and fun experience =)
