Here's a modest tip for easily rehydrating tobacco that's easy and not messy. I'm sure it's not an original idea, but I called it a hydration chamber. See the photo below: You simply get a larger container with a wide open mouth, and a second container that you can put inside. The larger container needs a top, preferably with a waterproof seal.
Now simply put a desired amount of tobacco in the second container or jar, pour some distillled water into the large chamber; put the second, smaller container with tobacco into the larger container. A tin of tobacco will float nicely in the large container and speed the hydrating process; the closer to the water's edge the second container, the faster the hydration process. Then just put the lid on the main container, checking and stirriing the second container with tobacco for humidity level. With a simple time, this will occur in a few hours, overnight for 2 ounces, depending on how much water you add. I've tried this chamber on three batches and it works wonderfully. Your main problem is getting the right size chambers: triy K-Mart or other stores where they sell in their houseware departments a contianer-withiin-a contaier rig. I think you will find thiis works very well.
