Tealight

Is it ok to leave tealight candles burning overnight? They will snuff out eventually right?

Not recommended, as you are not sure about "Jumping flames" some dust debris sometimes in the air will burn up and spread over to another flammable site. Worse if u put it in your room, all Co2 will definitely kill you when u are sleeping.

What will happened to all aroma therapist wont they be sue for attempting murder ? :D
