Aspergillum

An aspergillum is a special tool that people use in some religious ceremonies. It looks a bit like a small cup on the end of a long handle, like a fancy spoon with a stick.

When they use it during a ceremony, they fill it with holy water and then they shake it around, sort of like waving a magic wand. This helps the holy water sprinkle all over the place, blessing everything and everyone around.

The name comes from a Latin word that means "to sprinkle," because that's exactly what an aspergillum does! It helps spread holy water and bless people and places during important religious ceremonies.
