Hello guys, thanks for such a good response.
First of all, it is not an Hail or Ice stones, they're just like normal stones we get after digging the ground.
AFAIK, there's no mining work around, but at some places there is blasting going on. But I personally went there, and found that blasting stones can't reach more than ~500meters area. They are low powered blasts, not the heavy once.
They fall on specific space which's around 20-30 Sq.feet, never found elsewhere.
There is no possibility of monkeys doing this, There were no monkeys, or any kind of birds around the place when we saw the Hail.
I tried to research it all the way I could but found no solution, I'll post the pictures of stone ASAP.
Few years ago some other house in area has experiencing the stuff, but it wasn't happening since long time.
Finally :bleh:, no need to call India TV, they'll make it kind of "Black Magic", "Paranormal Activity", "Chamatkar"... :rofl: I want to find it out in right manner.
