Water from boiling eggs

[4kidsmom]

Hi ladies,

I am making the hard boiled eggs for our Easter egg decorating.  I thought I remembered reading somewhere that the water was good for something after it cooled off due to the calcium that went into the water?  Am I right?  What can I do with the water?

Thanks,
Merilee
