Yesterday's Bio Practical
It was the third bio practical I had. We tested several food substances to find out if it contained starch, reducing sugar, protein and lipids. For the starch, you should know, just add iodine. For the reducing sugar, we added Benedict's solution and for lipids, we had to add 5ml of sodium hydroxide and 5 drops of ClHO4. Warning!!! The 10% sodium hydroxide will dissolve you!!! For proteins, we added distilled water and something else.
I remembered we had to insert the test-tube into a 80 degree celcius water bath. There was once my friend's hand accidentally touched the sodium hydroxide. He said it was scorching hot. That was just 10%, imagine pure 100% sodium hydroxide. We sometimes inadvertently add too much chemicals and cause a huge explosion. Just kidding, nothing actually happened.
Practicals are always fun and enjoyable. I am looking forward to the next practical.

Chess Competition
I participated in the 60th Nationals Individual Chess Championship held at Teck Ghee C C two days ago. I won on the first round, lost in the second, won in the third, lost in the forth and fifth, and won the rest. There were a total of 8 games. I won 5 of them . Too bad I still could not get any prize. One of my friends (my classmate, Jia Hong) took part in the girls category. She also got 5 points, but I think she was one of the top 20. This is so unfair, they should mix the girls and boys category. The girls category has less competitors (42, compared to the boys with 179), and is easier to win.
Can you spot where I am? (hint: I am near the standing person whose back is facing you)
Showing off my Megaminx.
