I just bought (or, more accurately, my Mom just bought) a humidifier for my bedroom. It’s a cool-mist unit with an “ultrasonic transducer” to created the vapour. Pretty plain, pretty straightforward. While watching the mist this morning, an idea occured to me–adding a few drops of cologne or some other scent to the water to add a subtle hint of the smell to my room.
Can I do this? If not, why?
