Funny Hidden Stuff

Hello there, this was a book that I borrowed from SM All Saint's library..

The thing is, I was impressed and facinating by the architecture that shown

in the page u saw ( the picture )

I am impress by the technology they ( west counrty )

had way decades ago compared

to our lovely country.

The picture shows an AERATION

a dam that is use as a water filtration.
as you can see the second page of the book (right side)..the water were purify

by spraying it into the air.

the water particles were purify by the collision with oxygen.

...

at the end..water will be supply to residential =)
