The CO2 (dry ice) pushes out the O2 (oxygen). That is a pretty clever idea.

Just curious... if the dry ice is in the bottom of the bucket covered with wheat, how do you know when it's completely evaporated?

Sky it is on top of the wheat, read it again...

I think you can put the dry ice on top or bottom. I've seen folks suggest it both ways. I haven't done this....just read about.

I've always put a couple of handsfull of wheat in the bottom of the bucket and then set the dry ice on top and added the rest of the wheat. If you put it directly on the bottom of the bucket you risk possible cracking the bucket. I also forgot to mention leave a 2 inch head space in your bucket.
OK, got all that. Top, bottom, probably doesn't matter too much. But... without opening the lid to inspect (which would defeat the purpose, IMHO) how do you know when the dry ice has completely "melted", so you can seal the container?

I would think if the bucket is still cold on the bottom then there is still dry ice in there. Once the ice has sublimated then the bucket won't be cold.

On the canning idea before pressure cooking there was canning using wax on the topas a sealer
anyone know if this is for longer than a winter or just for one winter
respect

Canning using wax is still done. I don't use it because it's not a reliable way to can in my mind. However, as long as the seal is good and creates a vaccuum it should be good for as long as any pressure canned jar.

Wow... memory surge... my momma used to can strawberry preserves and grape jelly with a wax seal on top of the jar. Never did it with anything but jams and jellies, though. I think it was a cost thing...wax at that time was cheaper than lids and rings. Come to think of it, she used non-standard jars to can the preserves, so maybe the lids and rings did not exist for those sizes of recycled mayonnaise jars. She was big on reusing jars, and only had a couple of them crack from the heating. She had basement pantry shelves full of empty jars (and some full ones) when she sold the homeplace, (they went with the house) and I wish I had them now. I never liked digging the wax out of the top, though, 'cause it always left little crumblies of wax in the preserves. Thanks for the diversion down memory lane.
Everyone should have that same philosophy. More twinkies for the kid that way.
