A quick aside about Nalgene bottles: I bought a one-litre branded Nalgene-alike from my university bookstore for what I thought was the exorbitant price of $8.95. Turns out, that was the best nine bucks I ever spent (well, except perhaps for that four-pack of Flying Dog Imperial Porter, but I digress). What that green plastic bottle does is make it trivially easy for me to drink water — lots of water. I’ve probably doubled my water consumption (which has never been particularly low) since buying that thing. I’ve also stopped buying soft drinks just because I need something to wash down a meal, which I imagine has done wonderful things for my blood sugar levels.
I don’t, however, boil water in that bottle.

Good T-Nation article; thanks Matt. I passed this info along to Sunny, who was quite interested in it.
