We are studying weather in my classroom right now and my own kids get to be the guinea pigs for all activities that I am not certain will go smoothly with my preschool class. I posted this Instagram of our first attempt and immediately people were asking for more information. I asked my kids to help me re-do the experiment with step by step photos so we did a little more kitchen science to show you how to make a cloud in a jar.
Gather your materials. You will need a glass jar with a lid ( although a snug dish will work), hot water ( boiling works even better), an aerosol spray ( we used hairspray), and ice cubes. If you have a child capable of handling boiling water a pyrex measuring cup is great to have on hand as well.
Quickly spray the hairspray into the jar. The spray gives the water vapor a surface to condense into tiny cloud droplets. Some experiments use a match instead. Both work but boiling water was enough of a risk for one experiment.
Pop the lid on with the ice and watch the cloud form. This was our 4th time overall doing this and my 4 year old was still amazed.
