A CANDLE would set off the fire alarms? Those are some serious fire alarms!
Even a little tiny birthday cake candle?
The only other thing i can think of is if the coefficient of thermal expansion is significanly different, fill a balloon, and put it in the freezer for a while and measure it... But i don't know if if the difference between N2 and air would be measurable in any reasonable manner.
