Hi Mal,

your balloons probably were a bit old, they become porous with the 
years. But that is no problem, you just have to cook them a few minutes 
in boiling water (no joke!) and they are fine again - even after many 
years. We never had problems during our activities (DL0ART/am) except 
once when we probably didn't stir enough...
