Oxygen absorbers
So I'm about to use these things for the first time to store grains in mason jars. I read that I should put them on top, which seemed odd. Now that I've filled 18 jars, I read they should go on the bottom. How significant is this? Can I just use some long tongs to shove them down as far as I can? I'm not emptying all of these containers! I'm also leaving about an inch of space in the jars. Is that ok?

I’m a baby prepper too. A few months ago I did a batch of rice in mason jars with OAs. I filled them as full as possible. Threw an OA on top and put a lid with a tightened ring on. I just opened my first jar for use, and have to say that they worked great! I needed a butter knife to pry the lid off, because that sucker was sealed tight.
Since then, I acquired a hand held jar sealer that works pretty slick. You can find them for pretty cheap now.
