  1. Fill the large pot halfway with tap water.
  2. Place the smaller bowl inside so it floats.
  3. Turn the pot lid upside down and place it on top of the pot.
  4. Heat the water until it boils. The steam will rise, condense on the lid, and drip into the smaller bowl.
  5. Collect the water from the smaller bowl, which is now distilled.

It is also important to know how distilled water compares with other common types of water. This helps explain why it is priced the way it is.

Tap water is the cheapest option since it comes directly from your faucet. However, it may contain minerals, chlorine, or fluoride. While safe for drinking in most US areas, it is not suitable for appliances or medical use.
