Well, in this 9 days of holidays i have been doing some experiments and reseaching regarding the Garbage Enzyme that Xuelin taught me to do.
1st I collect at peel of the oranges that my family was going to throw away. Then i put it in a glass bottle then i seal it.
After a day I open it, "pissss" a gas run out of the container.... then i thought :"wow the peel f oranges release a type of colourless gas. Then i make some hypothesis:
Hypothesis 1 : Ripening of citrus fruits(oranges) emits a colourless gas
Hypothesis 2 : Decaying of citrus fruits(oranges) emits a colourless gas
Day 1(23/1/09)
I go do some research then guess what i find out....my 1st hypothesis is wrong because citrus fruits pass from immaturity to maturity to over-maturity while still on the tree. Once they are separated from the tree, they will not increase in sweetness or continue to ripen. The only way change that may happen after being picked is that they will eventually start to decay.
So i think that my hypothesis 2 is almost correct but wait....isn't that the decaying process of plants emits carbon dioxide, and guess what i smell? The smell of oranges...since when do decaying smells so nice? Oh well probably the particles diffuse between the air molecule, I guess that makes the smell so nice.
Day 2(24/1/09)
I prepare a solution of Sugar Solution using white sugars then i put about 8/10 orange peels from the glass bottle to a bottle of sugar solution that i prepared. The orange peels and sugar solution get about 6/10 capacity of the bottle. Then I thought of Xuelin's Enzyme Explosion, I very afraid that the mixture will burst out the bottle cause the bottle is very small moreover it is in my room. Despite that i don't want to mess my room so i wrapped the whole bottle with 3 layes of plastic so that is an explosion occurs i just need to throw the plastic away and no need to worried about messing my room.
Day 3(25/1/09)
I open the bottle cap, the "pissss" is heard again but where is the gas produce from? Is it the gas produce from the decompostion of plants? I don't think so because the sugar solution is hypertonic to the bacteria and microorganism. Then what produce this particular gas? I observe carfully, and I saw bubble were coming out from the orange peels. I guess there have been a chemical reaction but what cause it to react like this? My reseach and experiment are still carry on......

I've just asked my chemistry tuition teacher about the enzyme, and it turns out that my hypothesis is wrong. I'm going to write hers in my blog. By the way, you need not wrap it up in layers of plastic. It won't go off like a bomb. The 'explosion' (or to be more accurate, 'eruption') happens only when you open the cap. So don't uncap it in your room!
