The second day mirrored almost all that
happened on the previous day, except that the students were replaced with a new
batch consisted of the second-last and last classes. As usual, the students
were oddly fascinated by the cornflour slime (despite it being a relatively,
albeit very interesting (and fun) experiment). We were very impressed with how
fluent and eloquent the students were in English, and how knowledgeable they
are about the field of science despite only being 14 years old (I remember
being one and boy, did these kids on another level than 14-year-old me).
The
programme ended early today (really, it’s Friday though…) at around 12.30, and all
of us went back to our respective colleges happy, and hungry. A bit.
So as nothing much to update for today I would like to explain a bit about the scientific theory for certain exhibition. So firstly, the "Cornflour Slime". What is it actually? How come when you exert a force on the slime, it become a solid but when you put no pressure or force on it, it will become a liquid? Magic?? Scientifically corn flour slime is a special type of fluid that doesn't follow the usual rules of liquid behavior. When pressure is applied, it's viscosity increases (hard to flow) and at a certain point the slime can behave like a solid.

Next i would like to talk about the "Atomic Bomb". We present about what's really happened during World War 2 which involving the atomic bombs called 'Fat Boy' and 'Little Boy'. These two atomic bombs are very small but they managed to ruined Hiroshima and Nagasaki that time. Presentation about the black history is to raise awarness among the students and at the same time they can learn about the effects of radioactive substances on biological life.
Stability? What it means by stable? Basically we will say that being stable is being firmly established. We are less likely to change or fall. Yes fall. What factors that can prevent a structure from falling? Firstly, centre of gravity. The lower the centre of gravity, the stable the structure. Secondly, size of the base. the larger the size, the more stable it is. Next, mass of the object.The heavier bodies are harder to move and hence are more stable.
