MYOG camelpack bottle
I wanted to be able to use my powerade bottles with a hydration hose out of my bottle holder pockets on my Osprey Exos. no unpacking the sleeve inside for refilling, no washing the bladder, etc. 1/2" drill bit and it doesn't even leak upside down :)
Pretty cool bottle mod. The only thing I see wrong is how do you get the liquid in the final 2 inches of the bottle since the interior straw does not extend to about 1/4 inch from the bottom? Terry

It was a quick photo. i have pushed the hose further down now so it will reach the bottom. i am really psyched that the hose was tight enough through the hole to create a seal without anything extra like silicon caulk or something.
What prevents the bottle from collapsing due to vacuum? The Evernew adapters have a small valve in the lid.
nothing, though the powerade bottles are pretty stiff so they don't collapse but drinking might get harder? i haven't played with it a whole lot. Maybe drill a small hole and cover it with white athletic tape as a breathable membrane but won't let it splash out?
I would bet that if you sucked out a bunch of water and created a vacuum eventually the pressure difference would correct itself via the small gap between the hose and cap. I don't claim to be an engineer, but I've seen my son's baby bottles do the same thing through the *tiny* hole in the slow-feed newborn nipples. They're small enough that the surface tension of the milk won't allow drips more frequently than one every few seconds.
