- ===================================
-
- This keeps happening again and again and again and.....
- Time to get net.wisdom now.
-
- I leave a glass full of water near my window. Many hours later I see
- all these bubbles sticking silently on the glass walls. The bubbles
- seem to be smallest near the top, bigger in the center and sort of
- small at the bottom. Also, the number of bubbles seem fewer in the center
- when compared with those at ends.
-
- Well, why do these bubbles form? Why the size differences? Why the number
- difference? Hmmmmm, try it and then tell me: what happened and why.

- ps: I have seen this happening in industrial size vessels too - for you
- engineers out there. Particularly, in cooling towers.
