Have you ever wondered how simple things you use time and again work ? Don't think we are going to speechify something , but we will give you an account of the mechanism of a thing that is not as simple as it looks. If you have got a discerning eye then you will be able to see our point.
We are talking about your constant companion in the hot summers and when it rains. Yes you are right if you have guessed it to be the umbrella.
So next time when you hold it just observe its mechanism and check whether we have given you a true account of its mechanism.
