How to make distilled water is brought here for you.
Fill a 5-gallon (18.927 L) stainless steel pot about halfway full with tap water.
Place a glass bowl in the water. Be sure it floats. The bowl should not touch the bottom of the pot.
If the bowl doesn't float, remove it from the water and set around baking rack on the bottom of the pot. Then place the bowl back in the water.
Watch the water collecting in the bowl. This water should be hot but should not boil. If the water begins to boil, turn down the heat on the stove.
Create a condensation effect with a hot/cold barrier. You can do this by inverting the pot's lid and filling it with ice. When hot steam hits the cold lid, it will create condensation.
Boil the water in your pot. As the water continues to boil, it will cause steam to rise and condense on the pot's lid. The condensation will drip into the bowl. Allow the distillation process to continue until you have enough distilled water in the bowl for your needs.
Remove your pot from the heat and take off the lid.
Take the bowl of distilled water out of the pot of boiling water. Use caution when doing this so you do not burn yourself. You can allow the water to cool before removing the bowl if you prefer.
Allow the distilled water to cool before storing it.
These are the steps that you should take to make distilled water. So, next time that you are not sure of the health of the water in use you can make it healthy by these steps.
