How do you make sterile water?

To make sterile water, you have to maintain a temperature of 250 degrees Fahrenheit for a minimum of 20 minutes. This is achieved by the use of a pressure cooker. Follow the directions for removing the lid from the pressure cooker. You need a pressure cooker with a temperature gauge, clean water and a stove or a heat source.

1. Fill the pressure cooker with water

   Carefully pour the water into the pressure cooker. Cover the pressure cooker with its lid, and close it.

2. Put the pressure cooker onto a heat source

   Light up the heat source, and place the pressure cooker onto the heat source.

3. Observe the temperature gauge

   Keep a keen eye on the temperature gauge. The water must boil and remain heated at a temperature of 250 degrees F.

4. Maintain this temperature for a minimum of 20 minutes

   Once the temperature has reached 250 degrees F, maintain this temperature for a minimum of 20 minutes to make sterile water.

5. Pour the water into a clean container

   Remove the pressure cooker from the heat source. Pour the water into a clean container, and cover it with a lid. Let the water cool. Your sterile water is ready for use.
