A friend of mine does a lot of cake decorating using tubes of icing,
decorating bags I think they're called. She is having problems with her
hand strength, however- the icing is in some cases too thick to comfortably
squeeze out the tip on the bag. Unfortunately, apparently the thickness of
the icing cannot be adjusted (my first thought) as it's a production
environment and she cannot just add water to the icing. Is there any
mechanical device that is used to help apply pressure to this kind of bag,
to assist in getting the icing out?
