Query: Fun at first

I had a friend of mine who is a scientist analyze some of this so-called "milk." Did you know that it's 2/3 water?!?! And there was animal tissue in it, like some sort of pus or something. Plus, if you leave it open on your porch for a few days in the summer it will give off the most disgusting smell you've ever sniffed and will eventually become full of maggots. I think it is reprehensible that Amazon is selling this product as something safe to drink and I plan to boycott this website until this product is removed.
