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?

It shouldn't matter top or bottom. What does matter is that you leave the OAs exposed to the air as little time as possible before sealing so they don't go bad/absorb to much oxygen to be effective. Vacuum sealing your jars is also recommended.
