This white thick liquid, is corn flour mixed with water. Though playing with that mixture itself sounds nice, this "experiment" wasn't done to see how much we enjoyed it. This mixture strangely, is liquid-like and sticky at first, but after applying a small amount of force, it is able to almost immediately convert into a bouncy-rubber like substance. Apply even more force, like a punch, and it can feel like you're punching a brick wall. After that, i reverts back to a liquid state. Totally radical stuff, guess we humans can walk on liquid after all.
The next cool experiment we did was crystallization,we were split into groups and then we had to put coloured powder into a small amount of hot water in a cup, then lower a rock into the liquid using string. Then we left it in the chemistry lab for a week to settle and form. A week later, we went to recover our experiments. Other groups had their rocks completely encased in a thick growth of crystal, like so...



Our rock didn't change at all! Instead, crystal formed only above the rock, on the string...


A cluster of monoclinic type crystals

Here's a side profile, to better see what monoclinic crystals look like. It's a bit like staglagtites in caves.
Other teams had different types of crystals formed too,



After awhile we got bored of this beauty, and decided to kick it up a notch with the power of refraction.


Here are a few more pics of the crystals. Enjoy...




Credits go to Olivia for taking the higher quality photos. Anyway I'll just end this post with a picture of Brendan being......Brendan...

...and another one of Mr.Guoy's homework!Should be interesting....

Anyways time to put an end to this long one, Au Revoir all....
