Just a thought.....those small bottles that you find at the register....the ones that hold tylenol or motrin. They're about 2 or 3 dollars...after you use the medicine, they make nice 'waterproof' containers. I don't know how much waterproofness they have but I think that they should be good enough if you 'went swimming' with it.

I haven't yet figured out how much you can put in it for a PSK, but I'm working on it now and I'll let you know. Just some 'food for thought'.

Nalgene make some similarly sized bottles that ARE waterproof. Check REI, EMS or Campmor. I use them all the time for everything from cooking oil to medicine.

That is nice to know...my thought was just that these are available to 'almost' everyone. Easy to acquire and cheap. Just thought that someone could use the info.
