How are balloons stored correctly?
The balloons shouldn’t be exposed to severe changes in temperature or sunshine for a longer period of time: The balloons don’t like ultraviolet rays. The best storage is in a fridge. The chemistry laboratory isn’t a good place for storage either since solvents might corrode the balloons. Also avoid contact with dust or sand! The already prepared but not used balloon sculptures should be put down on a clean surface. Following the above mentioned points unused balloons can last for an almost unlimited period of time.
