Old Goat – I’m making a Faraday cage also 🙂 May I ask what you’re using to make yours? (Mine is beng made from a large galvanized steel lidded trash can, with thin yoga mats cut up and glued with spray adhesive to the inside surfaces as a liner, and metal HVAC-type tape by 3m to seal the lid closed once my spare small electronic items, etc., are put inside).
Muffy1938 – I accidentally posted the following information for you in the EveryDay Prep Check-In forum so I apologize if you’ve already seen it: “I also re-seal whatever I don’t use up right away out of a No. 10 can of dehydrated or freeze-dried foods. Usually I vacuum seal those (very dry) leftover items in glass canning jars using the attachment for my FoodSaver vacuum sealer. I recently got a special vacuum-sealable lid called a “That Seals It!” that is designed to fit an opened No. 10 can. You place it on top of the opened can and either use a small manual pump or an accessory hose and electric FoodSaver to pull a vacuum, thus re-sealing the can. It looks like a clever gadget but I haven’t tried it out yet. If you want to see a video of how it works, you can go to YouTube dot com and search for “That Seals It! Manual Operation”.
