To loosen Glass Stoppers. 



Some one of the following methods is certain to 

 prove effective: 



1. Hold the bottte firmly in the hand or between 

 the knees and gently tap the stopper on alternate 

 sides, using for the purpose a small piece of wood, 

 and directing the strokes upward. 



2. Plunge the neck of the vessel in hot water, tak- 

 ing care that the water is not hot enough to split the 

 glass. If the stopper is still fixed, use the first 

 method.
