Fitting the Tube into a Stopper
The tube passes through a bored rubber cork that closes the flask or boiling tube. Wet the glass and the hole first, wrap a cloth round the tube, hold it close to the cork and push it in with a gentle twisting movement; a dry tube forced in can snap into the hand. The free end then dips into lime water or runs under a gas jar.
