the holiday so far...
the first week of this holiday has been a rather busy one... going to sch thrice and NEA on mon, so four days out.
and band practices hasn't been quite good and at the pace we are now going, i dun think the concert will be magnificent... so i'm juz praying abt it...
and ya,, growing crystals yesterday... i learn to be PATIENT in a Chem Lab... starring into this magnetic stirrer which takes long to dissolve both potassium aluminium sulphate crystals .. which was quite OK... but the other sodium chlorate was so slow, adding bits and bits and bits... starting off w 20g, and it was quite cold ( i learn it gave out heat ) so it should dissolve but it didn't . so my teacher , friend and i insert bit by bit - 5g but sometimes i add 20g at one shot, so the magnetic stirrer had to stir more and dissolve, we could heat but all need to be dissolved first... and crystals grown - the good quality ones - will be the seeds to start off and grow many many crystals... and it will be come a product, and so that's a group project..
so band practices next wk, 2 days off hopefully and ya need to clear my hw asap...
