A second claim made in the article was that holy water may be mixed with unblessed water to make a much larger amount of holy water. Similar accusations arose on a Catholic discussion site in 2008, with the same broad characteristics as the Tumblr claims: A layman informed me that we could just combine a little of blessed water with a gallon of ordinary water to produce a gallon and a bit of holy water. How can I demonstrate that this is incorrect? It is erroneous to say that you may combine a little amount of Holy Water with other liquids. To refresh it, you may combine up to 51 percent Holy Water with 49 percent normal water. Holy Water must always be present in greater quantities than normal water.
