Fitting a Tube Through the Cork
Bore the hole from the narrow end with a borer about the same size as the tube, not a smaller one, because a hole bored in rubber closes up slightly. Wet the glass with water or glycerol, wrap a cloth round your hand and twist the tube in gently, holding it close to the cork rather than pushing on a long length of glass. A well-chosen cork seats part-way along its taper, with the narrow end inside the neck.
