they didn't tell me they're camping at the sc rm tmr too, thus i had to carry that creeping blazer with me today, lucky got cover, so can just throw anywhere
anyway, aio was fregging easy -.-, finished 1 hr before time and was freezing to death, in the end i went away early and rushed in half-way through chem lesson
chem was about the egg in the bottle, you noe how to get an egg into a bottle without pushin it and thus using the flame and stuff? the primary sch explanation whereby oxygen is used up is bullcrap, since a equal amt of CO2 is produced anyway. that was some qns tat the teacher juz refused to answer in pri sch, but the real explanation is some mechanism regarding gases.
anyway the last question was now tat you got the egg in, how do you get it out, and we went crazy and talked about how to use another bottle, burn paper in that bottle, w8 till the egg was half way between the 2 bottles and pull the bottles apart. tat was until we realised we could've juz turned the bottle upside down and heat it -.-
