Experiment-Chromatography

Last Tuesday i just carried out an experiment in Chemistry Lab that was Chromatography. In this experiment, we were going to 'tick' a dye food on the chromatography paper. Our Chemistry teacher, 笑大声 which created by Gim May or Pei Whey because our Chemistry teacher is LIM ONN LAM and therefore L.O.L=Laugh Out Loud -.-"

Ok then, he asked us to increase the concentration of the 'tick' on the chromatography paper so that the seperation can be seen clearly. Then few of us, just kept on 'tick' the food dye on the chromatography. Some of them 用尽吸奶的力气 to 'tick' it. =x

The appratus.

Before this, Loo already told me that this experiment is quite difficult to control and you have to control its concentration... bla~~bla~~bla~~ That time i just simply uhm... ahh... ooo... But who knows, last Tuesday when i was carring this experiment,

Choon: Chiu, easy job lar! Keep on 'tick~~tick~~tick~~' nia ma! My sister also know to do it
lar~~

But then here are the results as shown below.... -.-"

Experiment Failed

What the hell!! WHY?! WHY?! 笑大声! You better give me a reason that can sacrifice me!!

Choon:" Sir! Why like that de?!"
笑大声:" You have to put it straight!! If not the colour will run like this."

Ok then, i repeated the same experiment again. Like a stupid kept on 'tick' the food dye on the chromatography paper and here are the photos that second tried for me.

While waiting for it, just simply took some photo on the other's chromatography papers.

what the contrast..

But then... After few hours, my experiment failed again!!! Reason was i never straighten it.. Gosh~~ Ok! I do it next time!! What the hell~~ I took my results to my classroom and then i saw Loo. Then i showed him my results and he laughed at me! LAUGHED AT ME, YOU KNOW!!! What the LAUGH!! I burn your car baru tau!!

Loo:" How come your results like this de?"
Choon:" How i know! Kanasai~"
Loo:" You never straighted it lar!"
Loo added:" But then why your colour look so weird? The colour suppose to be very light only.
You 'tick' how many 'tick' on the chromatography paper?"
Choon:" Uncountable.."
Loo:" Who ask u to do that?!"
Choon:" 笑大声.."
Loo:" Nop lar! Maximum 3 'tick' only lar!!"
Choon was stund~ing
Choon:" He said just increase its concentration only?!!!!"
Loo:" Ya, but then if u increase the concentration, because of the length of the paper. Then when
the seperation 'run' until the top, u will see nothing.''
Choon:" What the xxx!!!"

But then, the day after tomorrow, 笑大声 said that everyone have to repeat their experiment because there were some mistaked for the concentration of the ethanol. Since the lab assistant is in somewhere else (kuburkan diri, rasanya) so we have to continue our experiment on next week.
