Step 4: Let us make 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 :)
