We all surely like puffed up hot roti in our meals!!! br But, I am sure not many of us have wondered about how that roti gets puffed up when we put it on the full flame. br br There is this scientific reason behind it which I have tried to explain in this video of mine that is the part of my YouTube playlist ‘In & Out of the Box Videos’. br br I have started an initiative since a few months to support you improve your CQ (Curiosity Quotient) and make you more innovative through my YouTube Channel. Hope you are finding it interesting as well as beneficial.
