Fireworks?

i heard some noises when i was washing my hands on 30th aug nite.

at first, i suspected something is wrong wif the water pipes in my kitchen. den i realised tat the cracking noises were coming from outside the window.

there were some lights flickering like a small explosion every few seconds.

i nearly called the police den i wondered if these were m'sian fireworks, after all, it was their national day the following day
