The Magic of Immersing Thread Into Ice

Well today we did have a very interesting experiment, some might think that this experiment is dull and way too simple, but when you really try it out, you will eventually realise that there is a lot of things to learn in science especially the fun way

The person in-charged for today's meeting was no other than Ong Meng Teck

So our aim today was to make sure that the thread goes through the ice slightly so that we can lift it

In order to achieve it, we use either Pressure concept or Reducing Melting point concept

For the pressure concept, we used 2 pendulum bob and tie them together with a thread. Then this thread is rest upon the ice thus providing the pressure needed.

As for the the Reducing Melting point, we used salt which in this case we used Potassium Chloride. By placing the thread on the ice and then pouring some salt on the thread, the salt will cause a reduction in melting point of ice thus the thread will go through the ice easily. When the water on the ice dilutes, the melting point is then restored to it's original value thus freezing back slightly.


Enough of points, now picture time

There will be more experiments to come in the future!
