drip filter

I convinced myself that purifying water at home is much cheaper than buying at the sari-sari store (that's the village version of the convenience store)... more convenient too, since I don't have to lug around a jug of water every few days. And so I ended up buying a drip filtration set (multi-stage filter) at the nearby mall.

It has a ceramic filter, which should remove the particulates from the tap water. Apparently, the pores in this filter are so small that even normal-sized bacteria couldn't get through! Then there's this cartridge with several layers: activated carbon, silica, and zeolite. Granular activated carbon and silica are said to trap the off-flavours and off-odours plus some more bacteria that are small enough to pass through the ceramic filter. Zeolite, on the other hand, acts like an ion-exchanger. Because of this behaviour, zeolite is used to attract heavy metals that are harmful to the body. Just before water gets ready to drink, it passes through a final stage where mineral stones are found. These stones are the nutrient-booster of the group since they "fortify" the water with important elements such as potassium and sodium. 

As I wait (impatiently) for the water to go into the lower tank, I remember my stay in Sydney Uni where I had to filter water as well... 

2006. My experiment was about measuring the particle size of starch polymers suspended in water. The machine I was using to take measurements was so sensitive that it could mistake dust (which tend to collect in water) as the target material. That was why I had to make sure that not even viruses could contaminate the distilled and purified water I was to use in my experiment. My water reservoir (distilled water) was way up above the bench; a long Tygon tube snaked its way from the reservoir to a collection bottle found on the floor. Atop this bottle was a filter that had pores smaller than the smallest viruses. Since the pores were really small, the filtration process was tediously slow: it took all day just to get enough dust-free water for sample preparation... I used so many filters because they kept getting clogged up by whatever was suspended in the water during filtration.

Back to 2011. Water flow is indeed faster in my home set up than in what I was using in school. However, it wasn't fast enough for me to stay up. I'm going to bed. Tomorrow, there should be enough water for taste-testing.

my top 10 life lessons from Suits season 1

I enjoy watching this series on TV called "Suits". It follows a strong mentor-mentee relationship. Harvey Specter (played by Gabriel Macht), one of the best lawyers in the city, gives valuable lessons to his associate, Mike Ross (played by Patrick J. Adams), the lawyer without the law degree. I find myself taking notes (and tweeting them) as I watch the different episodes.
While waiting for the July 1 premiere of the second season of Suits on Jack TV, I list down the top ten lessons that I gleaned from watching the first season of series. It's not surprising that many of them came from the great Harvey Specter. There are few things in there that came from Mike and Harvey's arch-nemesis, Louis Litt (played by Rick Hoffman), as well.
NOTE: if these sound like a lecture, it's because these are notes I write to myself for when I need them... and to whoever is reading this list.

Here we go:

Federico de Vera's brand of beauty at the Ayala Museum

On my latest visit to the Ayala Museum this year, I was able to catch the exhibit curated by Federico de Vera. I haven't heard of him, most likely because I'm not part of the art circles. I'm just an occasional museum hopper who likes to visit beautiful art pieces. This time, I was about to learn what beauty is, in the eyes of famous curator de Vera.
I was blown away by how he presented art pieces he picked up from other art collectors. Some of these pieces I've seen in other museums before. BUT, these are presented in a more striking manner... Instagrammable being the first word that comes to my mind. Spot lighting and subtle backgrounds really make the artworks pop. Walking through the different sections of the exhibit, I kept saying wow to myself. I liked the way that the curator presented every piece... he succeeded in putting the best face of each piece on display. There was a sense of meticulousness in the detail... not just dumping pieces together on a table or…

tinikling

Back in college, I used to play with the UPLB Ethnomusemblia, a group of students who liked to play traditional Filipino music as live accompaniment to the UPLB Filipiniana Dance Troupe, those students who performed Filipino local dances. Tribal music was what I learned with the group: music filled with textures of the sounds from kulintang and agong; the resonating sounds of simultaneously beaten gangsa; and the deep tones from the dabakan. However, I never learned how to play stringed instruments that are part of the rondalla. I attempted the banduria but to no avail. That's why I never learned to play the music for the tinikling; instead, I contented myself with listening to the rondalla people play the lively song.

Tinikling is the national dance of the Philippines. In this lively dance, the man and the woman imitate the movements of a tikling, a bird found in the country, over two parallel bamboo poles set horizontally on the floor. The dance is made more challenging as the b…
