Choon:" Ok or not?"
Loo:" Haven't finish yet lar! You have to wait the solvent is totally above the colour. Why u
take it out already? Put it inside again."
Choon was rushing to the chemistry lab again and quickly put the chromatography paper inside the specimen. At the same time, Loo was in the chemistry lab too. Since he was in the chemistry lab.. Wakakak!! I asked him to set up the appratus again... =x
Loo:" No wonder ur experiment will fail the experiment lar!"
Choon:" ??"
Loo:" Look at ur specimen."
Choon was looking very details:" What's wrong?!"
Loo:" You never tie the specimen tightly! Then the vapour is coming out!"
Choon:" -.-" Then i have to do again lar?!"
Loo:" Hola!"
Choon:" Kanasai! Ei, you help me to do lar.. =x"
For sure some of my classmates were there and kept on asking Loo that "Sir, how about mine?"
Nien:" Sir, how about mine?"
Loo:" Let it be! Don't take it out first! Let the solvent go higher.."
Choon:" The solvent wont effect the colour mieh?"
Loo:" Wont lar! U put it until tomorrow morning also no problem."
Choon:" Yalar! 你不要假厉害啦!"
Loo:" Yalar! The colour wont go higher already."
Choon:" Speechless." Since he is a Chemistry teacher.
Here is the photos that i did in 1st time and the dye at the right hand side is look like dark brown before the separation. Because of the length of the chromatography paper is limited so i had to throw it into the dustbin because after separation, it separate into 3 coulours which are blue, red and yellow.
2nd time, i used red and apple green as the dye which shown in photo 1. In this time, i really minimum the concentration! Oh ya! I wanna add something! Before we started our experiment, L.O.L a.k.a 笑大声 said something.Nien:" Sir, how about mine?"

LOL:" Actually you all no need to increase the concentration lar~"
Choon:" Then Sir! How come last week u said it is better if more concentrate?!"
LOL just looking around and he just considered heard nothing from me..
LOL continued:" Ok ar! Rememeber ar! Just tick 1 or 2 ticks only ar!"
What the =x!!!
Ok! That's all for today!
