Tiny Tower!


Tiny Tower

Janine Isabel C. Guico (Tau) & Alyssa S. Zoleta (Electron)


Lyssa S. Zoleta, IV-Electron 
When you meet Lyssa, the first thing you'll notice about her is her height. She is about 5'5" tall, with beautiful silky long hair. It might intimidate you at first but you'll be proven wrong. She is very warm and it shows through her radiant smiles. She is an independent and strong-willed person. If you think that's all, wait, there's more! Lyssa is very creative, thoughtful and a good cook too. Just wait until you taste her bread rolls and mango float. Yum! Lyssa is a very dependable and trustworthy friend. There's no one quite like her. I think she joined RAPD to try something new and to learn how to use her creativity to create new products. 

Janine Isabel C. Guico, IV-Tau 
Janine's a very shy and quiet - looking person, but once you know her, you'll see another side of her, the corny and fun-loving Janine. She's a very hard-working and responsible student, give her a hard task, she'll panic at first, but, will finish it in no time. Very nice, as people describe her, you'll find only a few people as considerate and as kind as her. I think she joined RAPD because she thought it might help her when she becomes a doctor someday. 

So how's our RAPD experience so far? The best! Believe it or not RAPD gave us an opportunity to finally try working in the lab. It was actually really fun coming up with new products and merging science and the arts. Who knew an STR elective could be enjoyable? We conclude by saying that not all STR related classes are STRessful. RAPD just proved that wrong. 

HOW ARE OUR PRODUCTS? Two hundred fifty grams of Talisay leaves were boiled in 2 liters of distilled water. The leaves were boiled for 20 minutes. After boiling, the leaves were removed and the water with extract was filtered. Then, 200 mL solutions with different concentrations were made. One with 100% extract, one with 75% extract and 25% distilled water, one with 50% extract and 50% water and one with 25% extract and distilled water. The ones with 100% and 50% extract were placed in the refrigerator while the 25% and 75% extracts were placed in the RAPD cabinet. 


How to make Talisay extract (crude method)

1. Hand pick newly fallen dried Talisay leaves and carefully hand wash them to remove debris.
2.Transfer to a casserole and then add water and boil for 45 minutes to release the extract.
3. Let it cool.
4. Transfer to a pitcher with a fine strainer to filter loose stem and leaves from the extract.
5. Add distilled water to dilute.

Results!

QUALITATIVE The extracts had a clear yellowish gold hue. It had a tea smell but after a week of storage the smell faded. 

QUANTITATIVE Five 200 mL solutions with different concentrations each were created from 250 grams of Talisay leaves and 2L of distilled water. A total of 88 pesos was spent for the distilled water.
