I was inspired by the all the ibles on making a "fast rope" for their paracord. After several attempts mine keeps getting looped around one of the other loops and bringing my paracord to a screeching halt. Then I remembered the way I store my old climbing rope. In a stuff sack! Just like the bags that swift water rescue folks use.
That got me thinking about a "bag" that was smaller than an old sleeping bag stuff sack. Along came the fast bottle!
Step 1: Shrinking the "bag"
I knew i could get a smaller stuff sack, but that was not something I had sitting around (and I am pretty cheap).
Then I remembered that lots of people were using the old BPA water bottles for survival kits, dry storage, etc.
I raided the cupboard and found a bike bottle of questionable plastic content (even though I REALLY love riding for the NCMEC every year)!
