Dahi handi (Pot of curds) is traditionally celebrated on Lord Krishna's birthday who apparently loved it and would beg, borrow or steal to get it. In the picture above you will see a pot hanging from the centre. Well, now it contains just flowers. Youth form the neighbourhood will form human pyramids and break the pot. The group that breaks it will be monetarily rewarded. Unfortunately this celebration has been taken over by political parties and become a reason for drunken orgies.
The picture above was clicked in Bandra east. The pot was broken late at night hence I do not have any pictures of the human pyramid.
