My favorite catholic lore is that anyone can make holy water in a pinch but the church puts dumb restrictions on us like ‘do this only if someone needs their last rites’ like I WILL bless this McDonald’s sprite and I WILL enjoy the crispiness of our lord and savior
Another bit is that holy water cannot be diluted. When I went to the Vatican the tour guide was explaining this, if you put any amount of holy water into any amount of normal water, the whole bunch becomes holy. This is how they sell Pope Holy Water in the gift shop. This is how I've been drinking only holy water for two months now. I am immune to demons.

It’s not actually any amount of holy water- according to the Church, the water has to be more than half holy water by volume. So if you take a half gallon+a few drops of holy water and a half gallon of secular water, you get one gallon of holy water, plus a few drops. You can then add a gallon of secular water to that and then you have two gallons of holy water. We’ve got a couple jugs of Pope Water in the linen closet at my parents’ house, because my mom used the heck out of this loophole after a trip to Italy in 2008. It was more than a decade ago at this point and we still have Pope Water. We no longer have that Pope, but by god do we have his water.
