5. Step 4: Heat up the salt water in the container under a bunsen burner. Cover the top of the aluminium container with a piece of aluminium foil wrapped around the wire in a shape of a spoon.
6. Step 5: Place a wet cloth over the top of the aluminium foil covering the container to provide a cool surface for the water vapor to condense onto the aluminium foil.
7. Step 6: The water collected at the end of the "spoon" is now pure distilled water.
