Would there be danger involved in heating air inside a balloon, to say 200°C or more, and then inhaling the expanded contents? I'm referring only to harmful substances leaking from the rubber/whatever else party balloons are made of.
Perheps a better phrasing would be: Will harmful substances leak from a balloon when heated, assuming it doesn't melt first, and what are said harmful substances, and even better what are their effects on the human body if inhaled?
