Sulfur Hexafluoride
A little reasoning exercise for you as to why this happens.
After making a guess, search up on that gas.

Population
Humm......
Reminds me of a disturbing thought on
the similarity between humans plaguing the Earth
and cancer cells destroying our bodies.

MIT Physics Course Introduction
I just downloaded this whole Physics course from MIT and it's really very interesting! The internet has really made the world a smaller and more accessible place. MIT is a top university in the world and now their lectures are all available for everyone who do not go there to view and learn. This takes learning without boundaries to a whole new standard.
Will be posting up videos from the lecture series in the near future. In the meantime, do take time to listen to the introduction by Dr Walter Lewin.

Genetically Modified
In fact, much of our food we consume daily has been GM.
Rice for example is mostly GM, and farmers have been doing it since the dawn of agriculture.
Farmers cross pollinate domestic rice with wild rice to reproduce certain genetic characteristic in them, for eg, the fragrance and resistance to certain pests.
Good or bad?
I guess its up to individual tastes and preferences.

Electric fence
By 302 students....HAHAS
Clip taken from UK Show, Brainiac, Season 1 Episode 4.
Electric Fence Experiment
Richard Hammond shows the Brainiacs how fun Electricity can be.
Also, yes, if you are in the air when the electricity goes through, you don't get a shock. You don't get shocked if the circuit (box to fence to person to ground to box) doesn't complete.
On top of that, the end where he ALMOST shakes Hammond's hand, he doesn't. Also, the slight gap in time between feet hitting ground and the shock can be attributed to the 1-2 second delay caused by the fence not being constantly on.

Natural Garden
Makes me feel better knowing that my son is doing a service to the plants when we can't find a toilet in time.
Liquid Nitrogen
Very Low boiling point of nitrogen means that it's boiling at room temperature.
Therefore, it'll rapid change its state and increase its volume.

"Chocolates cause outbreak of pimples"
I'm sure everyone's heard of this before.
You'll be interested to know if its true.

Interesting! Do you know how it is done?
Fantastic video! Saw this on someone's tweet and was amazed at how they did it...
The answer is very simple. Seriously very simple.
But the preparation is very complex.
Let us know if you know the answer.

Sec 3 Science Project 2009!
Yeah! It's the annual Pythagoras' Switch Project. I am beginning to look forward to this project as the students ideas are becoming more and more innovative as the years proceed. My aim to be able to flood youtube with the students' videos this year and hopefully come up with some ideas for TKK Young Inventors' award!
And finally one project from last year!
Have fun!

PUR water
AMAZING!
Clean and purify utterly contaminated water with one small packet
at a cost of only 10 cents per litre!?
Maybe they'll come up with a lemon flavoured sachet next time.

Heavy Newspaper
Definitely must try this at home! Pressure is a new topic that is added to the syllabus of Combined Science(Phy/Chem) and it is interesting to note that the value of atmospheric pressure is 100 000 Pa! That is a super huge number and it means the force per unit area is 100 000 N! That is an equivalent of 10 000 kg object sitting in 1 square metre of area!
