After wanting one for a long time, I finally found a large water cooler jug I could buy! (And thanks in advance for being the type of people who understand this kind of a quest, and for not making fun of me!) I have wanted a large, see-through jug so that I could see it growing and get inspired to put more in. And Home Depot was selling them (with water, of course) for $6. I'd just love to know how much money a 5-gallon jug will hold when it is full--I'll let you guys know in a couple years. Anyway, if anyone else wants one, now you know where to go!
