Today, we had Bio Practical. We were tasked to investigate the amount of starch and reducing sugar(in this case, glucose) in each of the solution in 5 different test tubes. As there is a bottle of Ethanol on the reagent rack (every bench for 4 has 2 reagent rack). Naughty Khye An put Ethanol on the test tube scrubber. The results are as follows:
Next he poured some Ethanol in to a small red plastic tub that was used to carry hot water beakers. Later, he torched the tub and the tub was aflame. The fire was quite out of control. Koong Jye tried to blow out the fire but it grew larger bcos he was like injecting oxygen into it. Khye an then used another tub and extinguished by pouring water over it. The tub, unable to withstand a large change in temperature, collapsed and instantly changed shape. I shall take a fotoo of it the next time i'm able to do Bio Practical, provided the Lab Technicians do not discover it earlier than us.
