Before Passover begins, many families will go around placing 10 pieces of bread around the home to symbolize the cleaning of yeast products or Chametz.
Many Jews will go around the home with a brown bag, a candle, a feather, and a wooden spoon. This kit can be found at any Judaica shop.
The bread is placed on the spoon and put into the brown bag and any crumbs left over is picked up using the feather. Once all the bread is found and placed in the brown bag, the Chametz then is burned.
By the night before Pesach begins, all bread should be out of the home.
