The Art of Coin Balancing

When we were done with drinking our blub-blub teas today, Cassandra, Nina, and I were sitting around, waiting for our small intestines to digest complex carbohydrates.

And suddenly

Nina started to balance her coins on the bench. It was a beautiful and complete set of coins.

From big to small... In proper order... Just like a homologous series.

$1, 50c, 20c, 10c, and..... 5c!

Too bad that the difference in Mr between two consecutive members of this family doesn't differ by 14...

I challenge of you to find a coin balancer as good as Nina!!!

By the way, some of you may have noticed something different whenever you tap your ezlink card in an SBS bus. Something purple and orange.

it's nice and bright, right?

And finally, for those of you who haven't seen a 4x4 cube before!

I managed to solve 3 layers! =D After that, I was simply clueless.

Nice view from this angle!

But look at this.

Top view.

ARGH! Oh how it breaks a 3x3 speedcuber's heart to see an unsolved cube. In the end, I just decided to mess everything up. Guess what? I can't even solve ONE layer now. Sob sob sob...

(basically you have to form all the centres, pair up the same edges, and when you're done with that, you can solve it using 3x3 formulas) SOUNDS EASY! Hehe.

To my 4/7 friends... Sigh. Mrs Chan has rained chemistry worksheets on us. (as mentioned in the previous post) So sad lah. But then again, practice makes perfect!

"What other people can do, you all must be able to do. What other people cannot do, you all must be able to do."-- Mrs Chan

So basically we have to do everything.
