after sch we stayed back for our phy makeup lesson..do the SPA again..
siying and me in one group...we do the heat capacity experment..
haiz...,we need burette to put 5cm3 water into the test tube..siling and i were so blur..then we just poured 0.5cm3 into the test tube with the salt..fortunately, we noticed our mistake immediately...another group which beside us were very 搞笑 leh.

in conclusion, today i finally feel that the physic SPA is fun...
