How can i make my own vinegar,any recipes? :-/

I don't know as there is much of a recipe. Just put some cider someplace that is not too cool and let it go. Make sure the container isn't sealed. When the CO2 comes off, it is go to go somewhere, glass jug on not. You may want to pipe the overflow into a water tight container, as it may foam over a little at first. A cork and some plastic tubing going into an open plastic tub is good enough.
