What happens if you put milk into a humidifier? It would most likely collect and curdle and stop up the humidifier and everything sprayed with the milk would smell like curdled milk and mold. Someone needs to post the results. This might be the best post ever on this sub. You get to clean the humidifier. I need to know too. Thoughtful face, sadness. Sadness happens. It'll probably smell after a while. Also not recommended if you have a cat. Thank you. This is horrible and hilarious to think about. Then you get sprayed with atomized milk. Don't know. But I'm curious about an ultrasonic one. Roon would smell like dead bodies days later. You move shortly after. This is one of the grossest things I have ever contemplated. Interesting method for sabotaging someone's home without leaving any evidence as long as you take the humidifier with you when you leave. Hey, y'all, ever boil milk? That, it breaks.
