How do Clouds form????

How are clouds made??? That was the question for today..... so we made a cloud by taking a 2 leader soda bottle cut it in half and then but very hot water in the bottom and put ice in the top with the lid on and upside down.... It didn'[t really form cloud but it made steam (or condistation built up between the layers)
which formed on the side of the bottle and then dripped water like a cloud...
