Headfirst at Home: A Cloud in a Jar

April 15, 2020

Have you ever wondered where clouds come from? Today, we have a project that will show you how they form! Create your very own cloud at home with this awesome STEM experiment.

As promised, we will continue to share with you easy, do-it-yourself projects specially chosen by our team of expert educators. From STEM, to art, sports and more, we will help your kids stay healthy, focused, engaged and entertained.

How It Works: By pouring hot water into a jar and trapping it, you create warm, moist air. As the warm air inside the jar rises, it is then cooled by the ice on top of the jar. When the water vapour cools, it wants to turn back into liquid, but it needs to condense onto a surface. The hairspray provides a surface for the water vapour to condense into tiny cloud droplets. Then, a cloud swirls inside the jar due to the circulation of warm air rising and cold air sinking!
