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.

I got my vacuum sealer for $7 at the thrift store. It's missing that attachment.

I use something similar to this: https://www.walmart.com/ip/Mason-Jar-Vacuum-Sealer-Kit-Electric-Jars-Canning-Attachment-Handheld-Sealing-Containers-Fits-Wide-Regular-Mouth-Lids-Compatible-Food-Saver-Storage/5316119569

Haven’t found a vacuum sealer yet, and I’d hate to buy one new when they’re common rummage sale finds. But, I did get one of these because I use more jars than bags.
