Ram Ram (*Greetings) to all of my brothers and sisters. I am not new to the Sanathan Dharam, but I have a few questions. I wasn't able to find anything online so I hope that someone can answer it here:

Why do we offer unbuttered/ popped/ popcorn to the Shiv Lingam?

And why is it that we pop popcorn the night before someone's wedding. It's usually the Fua's (Dad's sisters) who fry the popcorn, but why do we do it?
