This is Michelle from NTU, who has a blur queen personality and a love for biology.
Currently studying at the School of Biological Sciences.
I have my birthday celebration on 16 June every year.
Loves singing, reading, baking and eating.
Basically your good old plain Jane! :))
My sister to get a boyfriend New school bag Have A&W curly fries and root beer Donate blood New pair of pumps An overseas trip soon The tales of Beedle the Bard To push myself into First class honours Jog regularly Lose 2 kilos! Mend the emptiness in my bank account Golden flats from COTTON ON More tops! dresses light grey denim skinny Nice comfortable heels Trim my hair Belt Handbag/slingbag for going out Try charcoal mask Printer
Ever wonder about whether handwashing really helps to get rid of microorganisms, i.e. bacteria? Of course, with our naked eye, we do not see anything but obvious grease and dirt (if there is). Too bad we do not have microscopic eye, but at the same time, if we do have, imagine how creepy the world will look like. EVERY single surface you see, is covered with millions and billions of microorganisms, probably of every shape, size, texture, with/without flagella, etc. The mass of all the microorganisms in the world exceeds the mass of all plants, animals and humans added together! Amazing??
Anyway, back to the topic. During one of my lab sessions, we scrap a small portion of our palm (before and after washing) with innoculating loop and smear it on a BHI agar plate. For those who don't know, BHI allows most microorganisms to grow on it and form colonies. And this is the result I get:
See?! Before washing, there are so many microorganisms....... different kinds some more. *shudders* and let me tell you, mine is not the worst. The guy beside me had his plate full of different colonies!!!! ewwww. even AFTER washing. I must mind not to get anywhere near him, haha. And for those who don't know, the black dots are not bacteria! Those are marker ink, cos I'm counting the no. of colonies and didn't want to lose track.
After washing, no microorganisms! =))
However, this is of course an unfair experiment cos I use a kind of lab soap which specifically kills bacteria, not like those normal handsoap.
But I still wanna marvel about how much the soap actually works!
So next time if I ever want to hold anyone's hands, I'll make sure he/she washes his/her hands first. lol.
Lab is interesting! though lab reports are not. yawnsss. nites all =)
I'm getting increasingly nerdy! So if you are a fellow nerd and have a love for textbooks and shopping, do add me on msn: terrorist_gurl88@hotmail.com. :D
