Oxygen eaters are easy, get an old baby food jar and drill the lid full of 1/64th-inch holes like a pepper shaker.
Buy some steel wool with NO soap on it.
Cover it in salt and knead it up well.
Cram it in the jar and screw on the lid.
Be sure to place it at the bottom of whatever container you are protecting, ideally in an old sock.
Smaller ones can be made from old prescription bottles, Larger ones from defective canning jars, etc.
Moisture absorbers are even easier, pour some instant rice into an old sock with no holes in it, tie a knot in it, and chuck it in.
Old cornmeal does a respectable job as well. A jar such as the one I just mentioned works too.
Check your local hardware stores, many things are shipped with silica gel packs they only throw away, ask them to save them, don't worry if they are full, and put some in the oven on tin foil Just In Case, heat them for half an hour on 120 degrees to reactivate them.
Any more ideas?
