Seating and Boring the 15/11 mm Stopper
Push the narrow end into the neck with a slight twist until it grips, leaving part of it above the rim so it can be pulled out again. If a glass tube must pass through later, cut the hole with a cork borer the same size as the tube; the rubber closes in around the bore and holds the tube firmly.
