Hey if i was friends with the Ents, (like Merry and Pippin) then I would ask then for a drink or two every once and a while. I would soon become a giant like them! All though I like my size so I would probably just have a little to make me around Saurons hight (Sauron is about 9 feet tall). If you could drink the Ent water at the Ent Wash would you and why. Why would you dring the water for what purpos and if not then why not? Even if it is just a little bit to make your self 7 feet tall insteed of 6 feet tall.
If you guys are looking to enhance your appearance, being freakishly tall will not get you anywhere. I would not drink it because I do not need to be taller.
Ya that is what I was going to say. They probably did not drink it for a long enough time. Who knows maybe they had mushrooms growing behind their ears, haha.
