Heh, haven't been updating yeah.
I was just lazy to update lol.
OK well, firstly, Happy Belated Birthday to my Sis, whose b'day was yesterday.
Yeah, she's now 21!
Today lessons were as usual, then until CE period, the class went for lunch and went to Singapore Polytechnic.
Me, You Kang and Xun Xin didnt go as we had to practise our sciece buskers thing.
We went to look for Mr Lim Yuen Tuck and asked him for permission to use the lab.
Then he brought us there and got us our needed materials.
Then he left for class and we were left alone.
However, since we were left alone without a teacher, the lab assistant, Mr. Tan ( The middle aged man wearing specs ), tried to stop us from doing our experiment.
He claimed that a teacher must be around and that nobody will answer for us if anything happens.
He is like, so worked up, Its just a small experiment, heating a solution of Sodium Acetate( NaCH3COO ) and allowing it to boil for awhile then leave it in the freezer.
Its almost harmless, as long as we are careful with the bunsen burner.
Besides we are already Sec 4, and we've done heating experiments before.
Well after that he joined us and helped with the experiment.
He complained alot, about asking us who our teacher in charge was and saying they don't take responsibility blah blah.
After all, it isnt a school activity/competition, it's a private function.
He also didnt let us use the fridge in the Physics lab, claiming it will spoil it.
What the hell, so he gave us ice cubes and a tub instead and we cooled the solution inside.
However without a freezer, it wouldn't work as i guessed.
So the first attempt failed.
Then we went to find Mr Lim again, after his lessons, found him near the canteen.
He said he had to go out to buy something and won't be coming back, so he asked Ms Maybelline Tan to accompany us to the Bio Lab to do the experiment again.
Yeah, this time the lab assistant auntee didn't grumble much but just gave us our needed items.
Then we did our experiment and placed the solution of Sodium Acetate in the freezer and then waited for 40 Minutes.
While waiting, Xun Xin wanted to do the fireball stunt.
It's like using cloth rolled into a ball, spraying lighter fuel on it and light it and hold it in you hands.
Yes, in your hands.
It was supposed to be warm but not searing hot if you hold it by the bottom as the blue coloured part of the flame isnt that hot.
However, Xun Xin failed 2 times.
We slightly charred the table on the first attempt, and Xun Xin decided to hold itbetween his fingers and light it for the 2nd attempt.
Yeah and that, too failed.
He was able to hold the fireball for 2 seconds before throwing it into the basin because it was hot.
We concluded that You Kang brought the wrong fuel.
He brought Neptane, but the stated one is Butane.
The fire caused by Neptane was all orange, meaning it was hot, but the fire caused by Butane would be bluish colored at the bottom part, and it wont be hot.
Well, then we cleared up and took the Sodium Acetate solution from the freezer.
It was still in liquid form and by taking a small piece of Sodium Acetate Crystal and placing in a dish, when the liquid sodium Acetate comes into contact with the crystal, it forms " Ice " instantly, or rather freezes instantly.
We did it and it was a success.
We were glad for a moment, but, we used up all the Solid Sodium Acetate and were wondering where to get more lol.
The lab assistant (Mr Tan) made Ms Tan sign a document to allow us bring home the solidified Sodium Acetate, the one we produced in the experiment.
And then he went on claiming that it is whose responsibility blah blah lol.
Then we cleaned up and Xun Xin pulled a cloth, which a beaker was resting on, resulting in the beaker dropping on the floor and breaking it.
He paid $2 for it.
It was a really small beaker and it costed $2 lol.
After that, Xun Xin went to canteen to slack and me and You Kand went home.
Well, thats all then, i'm going for dinner now, so bye.
