Some of us are still waiting for Teacher to tell us how big the bottles are.

FWIW, I have 10 bottles. One 27 oz Klean Kanteen, a couple 40 oz Klean Kanteens, two 1 liter polycarbonate bottles, four 1 gallon jugs and a 3 gallon jug in my truck. Over 8 gallons. All to say that size does matter wink

BTW a liter contains 33.8 fluid ounces, not a huge difference from that wimpy 27 oz bottle.
