Gotta question.
When you are in need of water. You find a source but it is not the cleanest. You have nothing specifically for water other than Iodine, container and the clothes on your back. Is it plausible to filter the water through an article of clothing into the container and use ~ 10 drops of Iodine per gallon to make the water less of an issue to drink?
What does Iodine do in water? Was does it fix? What does it not fix?
