Q&A for How to Make a Cloud in a Bottle

No, it will not rain. The cloud will only condensate, causing it to just turn back into water.

If you do not have matches, use a lighter and a piece of paper, or an incense stick to make the smoke you need.

method 1 : non-toxic for inhaling and ingesting method 2 (using air freshener): non-toxic for inhaling, ingesting toxic method 2 (using hairspray) : toxic for inhaling and ingesting method 3 : non-toxic for inhaling, ingesting toxic (depends on the plastic)

No. It will disappear in five to 10 minutes as heat and water escape.

Water droplets inside the bottle react to either temperature change or the heat and pressure caused by squeezing with the droplet nuclei to condense into water droplets. These droplets are contained in the jar, so they form into clouds for a short time.

The best way to learn the science behind this experiment is with someone who understands the background and can tell you what is happening during the the whole thing.

No. Gradually the water vapor would condensate on the glass or just settle into the fish tank water.

Probably not. The cloud is more like steam, and it will mix into the air.

No.

No, they really don't feel like anything. Clouds are just like fog. The only thing you feel when you pass through it is the moisture/humidity in the air.

No. It will dissipate or it will float out and mix with the air or just condense back to water.

No. For that, you would need a much larger environment.

The cloud will stay for about 10 - 20 minutes, so make the most of it while your cloud lasts.

You can only make it in a bottle or other small closed area.

Usually, you would make artificial clouds by using a plane/biplane, but doing so causes more problems and actually does more harm than greenhouse gasses. It is very bad for the environment and can cause dramatic climate changes towards that environment.

You can use an empty plastic water bottle that still has a couple drops of water inside. Close the cap of the bottle and twist the bottle at its center. Twist it until the middle of the bottle is only a centimeter thick. The top and bottom of the bottle should be very full with air. Keeping the bottle twisted up, unscrew the cap and watch the water vapor escape!

I guess you could use a balloon; you just have to make sure that instead of the fingers of a glove going inside the jar, the inside of the balloon is going inside the jar. You also have to make sure you can lift the inside of the balloon out of the jar.

Yes, you need a clear plastic bottle, a small water bottle works best. I used a green one and you could see it but it was faint, so a clear one is best. Also, a small size works best.

This will cause the cloud to escape. The water molecules will separate and it will loose its fog-like structure.

You can simply use a plastic bottle. You can use a glass bottle if you want, but it is not necessary.

It will disappear in five to 10 minutes as the heat and water in the jar escape.
