You can do a pretty decent job with a ziplock and a water bath until you can afford one.

Put the food in the ziplock and submerge it in a tank of water up to the top of the bag while its still open. Then seal the bag while the lower part is held under water. Helpful to have an extra set of hands if you have someone available to seal while you hold the lower part under water.

Obviously not as good, but it does help.

Also, has no one heard of a freezer?

If you want to get fancy, vacuum pack it. I’ll admit, I cannot stand even the slightest freezer burn. It makes me gag immediately. Vacuum packing basically eliminates that.

Satisfactory isn’t bad either, but factorio wins in my book.

I’m not educated in this matter at all, this is just a guess with no basis.

A “cloud chamber” is a device used to detect radiation, and it has been that for a long time. Perhaps they wanted to distance themselves from that device, hence the strained acronym CLOUD.
