There's an even easier way that uses no sealent at all.  Use the
silicone airline tubing that they sell in most aquarium shops (it is
usually a translucent blue or green).  Drill a hole that matches the
*inside diameter* of the tubing (3/16").  Force the tubing into the
hole and pull it through with needle-nosed pliers until there are no
puckers or pleats visible in the tubing, then trim it off so that it
protrudes about 1/4" below the cap.  The tubing expands to fill the
hole perfectly.  This works better with larger caps, such as those that
come on the 2-liter size plastic juice bottles.
