What You'll Need:

  • Small metal can
  • Water
  • Salt
  • Crushed ice


Learn about Can Frost


Step 1: Fill a small metal can 1/4 of the way with water.

Step 2: Stir 4 tablespoons of salt into the water.

Step 3: Add enough crushed ice to fill the cup, and stir the solution.

Step 4: Observe what happens on the outside of the can.

What Happened?
The cold solution in the can lowered the temperature of the can. When the air outside the can came in contact with the cold can, the air's temperature also dropped. The amount of water vapor the air can hold depends on the air's temperature; it cannot hold as much water when it is cold. The water vapor condensed on the cold can, and the low temperature made the water freeze and form frost on the outside of the can.
