As kids, in winter, we used to sneak into the local catholic church and place a large snowball into the holy water dishes that everybody was blessing themselves with on entering and leaving.
Maybe the catholics thought it was a miracle, as the level was going up instead of down, and gave their faith a bit of a boost. Anyway, that church was always packed, so who knows? Maybe my snowballs kept them coming back for more!
But, water is water, and nothing else, no matter how many great and glorious religious celebrities have done hocus pocus over it.
