View Full Version : water bottle warning
My brother who has a penchant for weird experiments told me about the differences between carbonated beverage containers and non carbonated containers. He took a peice of dry ice and placed one in a pop bottle, and the other in a water bottle (evian, dasani aquafina what have you) apparantly the water bottle ruptured first with a linear tear along one side. the pop bottle Detonated some time later with a random appearing rupture point. apparently the water bottles use a linear laminate and the pop bottles are a "crossover" type (I don't know the material science lingo here).
So my question is this: Has anybody noticed a difference in durability? I know that pop bottles "feel" more substantial than the other, of course so do Gatorade bottles, which hold a non pressurized drink. Just curious. Comments?
Hmmm, problem is, Soda bottles are meant to hold things inside, pressurized. How well will the hold up to a puncture without said pressure reinforcing the skin? I'd still vote for pop bottles though.
I'm using 750ml plastic flasks from the liquor store, I don't know how tough they are but they're flat so they fit in my side pockets better.

I sometimes boil my water to get out the nasties. Not being a patient person I tend to pour the water into the containers long before it has cooled. I carried Aquafina bottles on one hike and poured the water in, as I do with the soda bottles, and the bottle shriveled up and squirted most of the water out. From that day forward I have carried soda bottles only.
Redbeard is right about the bottles being able to withstand pressure. It not only has to withstand the pressure form the carbonated beverage, but it also must withstand pressure of the co2 that is injected into the bottle during the filling process. This step is not necessary when water in put in the bottle, so the bottles donít have to be as sturdy. I would say that if you do not mistreat your bottles as I do, the water bottles should hold up to normal trail usage. I like Redbeards choice of bottle also. It is a flatter bottle and think of the enjoyment of emptying it in preparation for the alcohol/water conversion. It's a win/win situation.
