I made distilled water at home to top up my car battery and I'd like to share my experience.
DIY Distilled Water in Four Steps
There are many reasons you may want to make distilled water. I needed to make some because my car battery needed to be topped up with water, and I read that it is best to use distilled water to do this. After doing some research, I found out that it was relatively simple to do this, so I went ahead and gave it a try.
What You'll Need
- Stainless steel pot.
- Heatproof bowl.
- Glass pot lid, larger than the pot you are using.
Note about ice: Regular chunks of ice from an ice maker are fine, but a large block might be easier. I filled an ice cream container with water and froze it, making a nice, large block of ice that worked well.
Step 1: Fill the Pot With Water
The first thing that you want to do is fill your pot with water. Regular tap water is fine. I filled mine about a quarter of the way.
You need to leave enough room in the pot so that your bowl can float on top of the water but still have room to place the glass lid on top of it.
Step 2: Place the Bowl Inside the Pot
The next step you need to do is place your bowl inside the pot. Like I said earlier, the bowl must be heatproof. I used a stainless steel bowl, but you can also use a heatproof oven bowl.
The bowl must float on top of the water and should be smaller than your pot, or else it will not fit inside. This is where your distilled water will end up.
Step 3: Cover the Pot With a Glass Lid
Cover your pot with a glass lid (placed UPSIDE DOWN) and bring the water to a boil. The glass lid must be placed upside down, as we will be placing our ice on top of it in the next step.

Your glass lid cannot have any holes in it. If there's a hole, it must be covered or must be sitting on the outside of the pot. You do not want the water that melts from the ice to drop down into your bowl.
Step 4: Place the Ice on Top of the Glass Lid
Now that your water is boiling, you want to place your ice on top of the glass lid. The steam that rises will hit the cold glass lid, which will cool it down and turn it back into water droplets.
The droplets will fall down into the bowl below: that's your distilled water!
Note: You may also need to remove the water that forms on top of the lid every now and then as the ice begins to melt.
The video below shows you step-by-step instructions on how to carry out this process.

Thanks glad it helped

Wow, that's much more complicated than boiling water, but I'm proud to say I know how to distill water now.
