Holy Items for Blessing (Aspergillum, Aspersorium, and Incense Boat) - Catholic Stock Photo

An aspergillum (less commonly, aspergilium or aspergil) is a liturgical implement used to sprinkle holy water. It comes in two common forms: a brush that is dipped in the water and shaken, and a silver ball on a stick. Some have sponges or internal reservoirs that dispense holy water when shaken, while others must periodically be dipped in an aspersorium (holy water bucket).
