Why do cookies burn on different cookie sheets?

Scents will linger in the air and seep into fabrics (clothing, cushions, drapes, carpets, ect.) and stay around. The type of scent will determine how strong it is and how long it remains for. The smell of burnt foods and smoke are both very strong and will hang around the hosue for a while. To get rid of it, open up some Windows and let a natural aire flow through. Try washing something, like a rag, if it touched the burned food. Throw out the burned cookies and take the trash out fo the house.
