Let it breeze ! Let it rain

A moment back when I was busy reading short and fastidious stories in  my discreet yet talkative friend ,Tinkle comics ,I  came across few questions and facts related to them. Two of them were related to rain so I couldn't stop my itchy hands and mind from blogging about this.
The Niagara Falls flow throughout the year,without going dry even when there isn't any rain.howz that?

1.    So my discreet yet informative friend explained that the falls constitute of 2 waterfalls  on either side of the American border .
2. The Niagara river  and Lake Erie constitute the water mass of the Niagara Falls.It continues to have water throughout the year as summer doesnot dry up the huge water mass.

•  In winter, the severe cold turns the water to ice making it appears dry .
• 
  
• 
  
• On few occasions ,tthe waterfall over american falls was totally blocked by ice and ceased to fall. But only once, from March 1848 has thus happened to the much larger Horse -shoe falls.

Umbrellas are made of cloth how do they protect us from rain?

•    This is possible because of the property of surface tension.
• Thin films of water cover each  and every gap b/w the weaves of the cloth .
• The gaps are so small that the surface tension is adequate and so the rainwater finds it difficult to penetrate the film .
• The second property is that the water flow takes the path of least resistance.
• The dome shaped structure of the umbrella lets the rainwater flow down the slope
• .Water cannot accumulate and penetrate the water film .
• You can experiment by holding the umbrella upside down and see what happens -see how long the film can resist  as the rainwater accumulates in the umbrella cup thus formed.

                             My view! ...Which you never knew!
Honestly , speaking I never got such kind of doubts over any science . It might be due to my hatred towards physics lor  my affection towards the literature . Whatever it is ,I felt it was informative.But I couldnot control my goat from grazing off at certain places like the following:

• The Great Lakes are a colleCTION of freshwater lakes located in northeastern North America, on the Canada – United States border. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario, they form the largest group of freshwater lakes on Earth by total surface and volume.^[1][2] The total surface is 208,610 km^2. 

• The countries like the U.S.A. and Canada which have really scarce population are blessed with the largest group of the freshwater lakes whereas developing nations in Asia inspite of having much more lakes and rivers have millions of people who are deprived of drinking supply .
• This is mainly due to the disproportion b/w the people and the water ther ,claims some of the environmentalists< envi Ron Mental ists>. Many of the people reading this may be of the same category but I literally mean the word.
•  I ain't demeaning the cause but noway supporting it with a flag in my hand shouting 'Save the earth ' where the poster has a globe with a tear rolling off from its so called eye.
•  Blaming is  really an easy game where you can casually pick a problem and protest saying that this could be better if that had not occured etc etc..In fact one must face the challenge and end up finding a solution and paleeeeez no blame game!  

^{REVERSE OSMOSIS"}

•  Science has spread its feathers in every phase of life and we still are in the pre-historic age where we hardly had knowledge and technology .For example, reverse osmosis mechanism is used in Gulf countries to make the hypertonic saline seawater into hypotonic fresh pure water. There are many such mechanisms where you can obtain drinking water from saline water.

1. And umbrella! It remained the object of my fascination not due to its structure and function but its comical use in cinema.The umbrella dances in Bollywood movies which used to top the charts make me roll on floor when I watch them now.Especially , 'Naa jaane kahaan se aayi hai...Kisi ke haath na aayegi yeh ladki ' from the movie Chalbaaz starring actress Sridevi where the actress dances in the rain wearing a raincoat and waving the umbrella!  My sincere advice to such personalities is use an object only when it is useful ...

^{I refer to such personalities splly ;)=>}

Wishing you a rainy day ahead...
