How can I get every drop of glue out of the bottle?

The easiest way to get every drop of glue out of a glue bottle is to turn the bottle upside down and stand it tip down in a cup or a jar. Allow the glue to flow to the tip. Keep the glue stored that way until all glue is gone. You can also use a cotton swab, toothpick or skewer to help get all of the glue out of the bottle.
