Just curious how many of you have given thought to the amount of water you can make with just the contents of your PSK...

Personally, I have a vial with 20 iodine tablets and 2 gerber bags. If I fill up the bags to 8 oz (just at the end of the vertical lettering on the right side) and use one of my razor blades to cut the tablet in half then I can get 10 quarts, enough I think for a healthy 5 days.

20 tabs, cut in half = 40 half tabs. 2 tabs treat 32 oz, therefore 1 tab treats 16 oz, furthermore a half tab is good for 8 oz. 40 half tabs at 8 oz apeice gets me 320 oz, or 10 qts.

Any small discrepancy in the halves (i.e. one part being less than exactly half) can be rectified by a longer contact time, hence the two bags - make a bag of water and let it sit for an hour+ while you are drinking from the other.

this doesn't include boiling with 5 sq ft of aluminum foil, my back up which could technically provide unlimited safe water. the tablets are definitely easier though...
