A drop of water

In Paul Turner's Blog by Paul Turner

Q: Many thanks once again for your guidance in these liturgical matters.  

I have noticed at the preparation of the Altar that a drop of water in placed in the presiders chalice.  What caught my eye is that a drop of water is placed in the Deacon’s chalice.   Is there a change that took place and I was not paying attention?  

Thoughts please.
