I'm thinking/hoping along with Susan, that it might weep (i'm in the hospital pharmacy as i type and just a few minutes ago spilled some water accidentally on my Sahara Pants---100 pecent nylon--and the water beaded up and ran off) a bit but hold enough to get me to the next water source or keep in enough to be treated so i can 'camel' up....of course if i had some chia seeds on hand 'cameling' up would be much more successful.
