Why turn jars upside down after canning?
The thinking behind the inverting is that the jam/jelly—being still at a temperature to destroy spoiler micro-organisms—will sterilize the underside of the sealing disc, and the little amount of air trapped under the lid. A vacuum can form if the jars are hot and the contents are at least 165 F/74 C.
Can didn’t pop when opened?

What happens if you under process canning?
The product will be under-processed since air is not as good a conductor of heat as water or steam. The jars also may break or explode.
Should bubbles come out when canning?
“When air bubbles are not removed, the air trapped by the food will essentially add to the headspace. Too much headspace can lead to seal failures.” Opt for wooden or plastic tools (like Ball’s official “bubble freer,” shown here) when shifting the contents to remove headspace.
How long does it take ball lids to seal?
