## Step 4: Let us make clouds!

Now here comes the miracle moment! Creating clouds.

Squeeze the bottle one more time as hard as you can! This dramatically increases pressure and temperature of the water vapour inside then when you release, prepare to be dazzled! This can be repeated many times and then the cloud can be squeezed out of the bottle.

You've created true clouds inside a bottle!

Well done and I hope you've enjoyed :)

<p>awesome</p>
what do you use for a lighter?<br>
Neat!
if relative humidity is around 95-100% here it works without water, just a damp bottle
First thing I thought of when I saw this: &quot;Oh hey, Terraria!&quot; <br>Second thought: &quot;Oh wow, this is super-cool!&quot;
What temperature does the water need to be?
May I quote from step Three of Cloud In A Bottle by Nanovirus: &quot;You will need to fill the bottle with a small amount of water, temperature and clarity isn't important.&quot;
the reason i asked is because i tried this shortly before posting this with cold water and nothing happened. the smoke from what i was using as condensation nuclei was the only thing in the bottle. maby using warmer water would work better?
Did you squeeze the bottle a few times without the nuclei in it before hand?<br><br>This increases the humidity in the bottle and allows water vapour to form.
yup. i followed your Ible to a T. you think it could possibly be certain chemicals in the water that are in the water where i am at the moment? i even tried to put a little pressure in the bottle and then squeezed it a few times and noting happened.
Oh, I am sorry to hear that you're having trouble. The other factor I could say is to really try and get as much CN (condensation nuclei) in there as possible. The more there is of that, the more surface the water has to cling to therefore meaning the more cloud you're going to produce &lt;: ) <br><br>I hope this helps!
i may just be doing something wrong or maby its just my surroundings. my house is pretty cold to start with. ill figure it out and let ya know how it goes.
Another similar variation to this is (If you know how to make a water bottle cap burst but twsiting the middle to trap the air in a more confined area, its a teen thing) Well what you do. Water bottle with an inch to inch and a half of water, preferably one with concave middle. Twist it up in the middle nice and tight. Swish the water around in the base, then let go. If done correctly, the bottle will immediately fill with &quot;clouds&quot; :D
That's a nice demonstration and explanation.
Thank you Kiteman! :) Also, I thank you for the video embed as I found it somewhat tricky to understand how to do so.
Not a problem. It's a tricky thing for non-pros at the moment.
