    If you have a freeze dryer, you can take it one step further by making dehydrated instant water: carefully transfer the boiling water into the trays, then run the freeze dryer until all of the water has evaporated. Whatever is left is compact and easy to store, with a practically infinite shelf life. To turn it back into water, simply add water and stir thoroughly.
