Instructions
Fill a metal pot with water until it is halfway to 3/4 full. Place it on a stove top burner.
Set the burner to a medium heat setting. Allow the water time to boil -- steam will begin drifting off the water surface as the temperature approaches 212 degrees Fahrenheit.
Remove the pot from the burner and carefully place it on an unheated burner. Wait until the boiling activity ceases and then place a vented cover on the pot. Return the pot to the heated burner -- when the water returns to boiling temperature, the steam will forcefully pour from the vents since it will have less space to escape from.
Turn off the heat and allow the water to cool before pouring it down the drain.
