Trick or Treating (Spoon-hitting) in Persian Culture

The household put some coal, as the sign of ill omen, and some salt, standing for evil eye, plus a cheap coin, signifying poverty, inside an earthenware jar. They turn the earthenware jar around their heads one by one. Then, one of them throws the jar over the roof onto the alley. Thus, ill omen, evil eye and poverty are driven out of the house.
