Fill the Instant Pot with bones, vegetables, water, salt, and vinegar.
Press "manual" on the Instant Pot and adjust the time to 120 minutes. Put the lid on and make sure it is set to sealing.
Once the Instant Pot is done and the pressure has naturally released, you can strain the broth.
Get out a ladle and a funnel if you have one and start filling the mason jars (or other container, preferably glass) with the broth.
Once the broth has cooled down well enough for you to handle the jars, put them in the fridge until you are ready to use.
If you used enough chicken bones and not too much water, you should have a broth that is full of gelatin and will wiggle like Jell-O!
