Do you tire of using your hands to haul around clunky, inconvenient bottles of liquids? Then fret no more, for you will soon be a fretless water player with the awesome Five Minute Bottle Holster.
Step 1: I Am a Poet. I Eat Lions.
This is really simple. You need a set of clips (you can salvage these off of a dead backpack, get them from the fabric store, find them lying around your kite loft, whatever.) You will also need about ten inches of nylon strap to go between them, an O ring just big enough to fit around the neck of your favorite drink bottle (or you can make your own by cutting down a large O ring and resealing it with superglue.)
Step 2: Capture the O Ring
Run the nylon through one of your clips, fold it over onto your O ring, and sew.
Step 3: Repeat Ad Lib.
Run another piece of nylon through the other clip, and sew to make a loop that will string onto your belt. If you want to get fancy, you can heat the cut ends of the nylon to prevent them from fraying.
Step 4: You Are Now Done
Enjoy the fruits of your labor. Run a lopsided marithon, or use your hands for more things than you ever thought possible while carrying a bottle. Take a load off.
