TEA ADDICTION
Got caught red-handed today by Michelle and Nadhi buying tea at take-away. (stalking together??? *gasp*. lol.)Ah well. Tea to me is like Subway to Nadhi.
So what if I love tea. Anti-oxidants(green tea) present, so that's a good thing right?
Maybe I'll be able to try every single one on the take-away menu before i leave Taylors :)
I bet Tiffy is snigger-ing evilly reading this.
HELIUM BALLOONS
Since Ashveer's to lazy to post this, I might as well.
Yesterday, Bio class started on an extremely entertaining note when Jeremy succeeded in inhaling the gas from the balloons he and gang(jin howe n karan) obtained from who knows where.
And of course, Helium being less dense than the usual air, you know what happens.
Anyway, some of the things said includes;
-"I love Bio"
-"Bio is Fun"
- and several responses to Ms. Lourds' comments
The Science behind the 'voice'.(p.s. not confident accuracy-wise)
Contrary to what most think, inhaling Helium does not significantly alter the pitch of your voice.
There may only be a SLIGHT change in pitch being that Helium is of lower density and 'fills' our vocal chords less than air. However, the frequency of vibration of our vocal chords are still the same.
Our voice is produced from the vibration of our vocal chords(influences PITCH) AND the vibrartion of the air in the vocal tract(influences TIMBRE).
Now, TIMBRE can be defined as the 'quality' of a sound. We use this in our everyday speech, too differentiate sounds like 'ooh' and 'ahh' when we speak(articulation, basically).
What less dense He does is INCREASE the speed of the sound we make. Since v=f x wavelength,
and we study physics, you know what happens to our RESONANT FREQUENCIES (yes, the one from the vibration of the He molecules which is caused by the vibration of your vocal chords).
So, this effects the RESONANCE greatly and thus the TIMBRE, a.k.a distortion of the frequency pattern of our voice(the sound we make is actually a pattern of several frequencies)
Tadaa, the 'Donald Duck' voice.
Though, I admittedly am puzzled whether as to the 'squeaky' voice is due to lower resonant f thus less power or otherwise. Do leave a comment if anyone does find out (thanks!).
P.s. Can't believe I'm doing this. Should be doing math hw or chem. T.T Sigh sigh.
Should you feel hardworking, you can check this out. Don't forget the link in the link. LOL.
and yes, reading it did give me a bit of a headache, but hey, I was curious. Hmm.. might kill me someday. Woof! Oops, I meant meow (moment of extreme lameness).

On a different note... (Get it?! Omigosh, bad pun. I'm getting lamer day by day)
Finally visited little Akiba last night. It was interesting.
Saw Kay's and Jun's 'perverted look.
Jun won Kay at arm wrestling.
Feeling like condemning a certain person but finally decided not to waste my time.
