The Weekly Troll:
This week is quite trollish
1) Lemon Tea
-Going for physics practical-
"Hey I put my lemon tea in your bag ar."
"Your gonna forget about it."
"No I won't"

........ After lab, back in classroom
"Oh ya, where's my lemon tea?"
"......Opps.... I think I left it in the lab......."
"....., Aiya, never mind, $1 nia.
"Oh really ar?"
-Takes out lemon tea from bag and takes a gulp.-

....-Lemon tea on table-
"!!!!!!!!!!!, OH YA, THE BARIUM"
*GG face* (Practical had radioactive barium)
"Dotz..... Eh, it's all you all drink one ar, I never even take a single sip."
-Pushes bottle to edge of table-
"Aiya, since you don't want to drink the barium drink, I help you drink."
-Takes another gulp-
"........ Did I just get tricked again?"
*lololololololololololol*

2) English Lesson
"There is a skill, whereby you can be biased, and yet present your ideas in a seemly reasonable way."
"That's trolling."

3) Chemistry Practical
Given four unknowns, which are either ethanol, acetone, propanal or benzaldehyde in any order, use Iodoform Test, Silver Mirror Test, Fehling's Test and Potassium dicromate test to determine their identities.

-OFFICIAL WAY-
Get the four unknowns, do all four tests on each unknown, and

	Iodoform Test	Silver Mirror Test	Fehling's Test	Potassium Dichromate Test
Ethanol	+	-	-	+
Propanal	-	+	+	+
Benzaldehyde	-	+	-	+
Acetone	+	-	-	-

But then chemical tests tends to screw up... so...

-TROLL WAY-
Materials: Water, hot water, test tubes, unknowns

1. Add some unknown to one test tube each and add water to each of them. Acetone and Ethanol are miscible with water(lets call them Pair A). Propanal and Benzaldehyde are not(Pair B)
2. For Pair A, put the two into the hot water, actone boils first.
3. For pair B, look at the water-unknown solution, Benzaldehyde is denser than water, so it "sinks", proponal is lighter, so it stays on top of the water.

There, you've identified all the unknowns, without a single chemical test.

Extra: "Americans are typically exposed to more radiation than the rest of us, because they have this thing called freedom of speech, so there's a lot of hot air around, and that causes radiation."
