Boring the Size 3 Cork for a Tube
When a delivery tube or thermometer has to pass through the cork, bore the hole with a borer slightly smaller than the glass, so the wood grips it once the tube is in. Wet the glass, hold it close to the cork in a cloth and twist it in gently rather than pushing on a long length of tube.
