Frost can form when the ground temperature drops to 32 degrees or colder. Water vapor condenses and freezes – creating frost that you see on yards, cars and other objects. You can simulate this process at home with a few simple items!
- Metal can
- Empty and clean the can. Take off the label.
- Put the ice in the can.
- Add salt to the can, shake it around.
- Watch frost form. It may take a few minutes for this to happen.
