Basically the wife and I gave the packets to all of our families to help with their 72 hour kits. All you need is a water source. Whether it be a river or water on top of a pool cover. I think this idea will help more people in the world than any other one.
IMO the church should invest in this heavily and make it available through their distribution centers. Even missionaries in 3rd world countries this would be a great help.
