Kids as young as preschoolers will be able to visualise the process of rain falling from the clouds thanks to the shaving cream clouds and bright blue rain used in this simple science experiment.

How do clouds drop rain?


So before you get into this cloud in a jar science experiment, here is the science behind how real clouds drop rain. Clouds are made up of millions of tiny water droplets. When these droplets of water get too heavy gravity makes them fall down as raindrops.

In this cloud in a jar experiment your cloud is make from shaving cream. Food colouring (rain) is then added to the cloud. As more and more food colouring is added to the cloud it begins to get heavy. When it gets too heavy the rain (food colouring) falls into the jar.

How do you make a rain cloud in a jar?


STEP 1: Start by adding water


Fill the jar with cold water about ¾ full. You’ll want to leave some room for the shaving cream.

STEP 2: Add the shaving cream


Squirt a thin layer of shaving cream on top of the water making sure there are no holes. The shaving cream represents your rain cloud.

Shaving cream does rise a bit and you don’t want your layer of shaving cream to be too thick so be careful not to add to much. If you do add too much not to worry, you can always scrape some off using a plastic spoon.

STEP 3: Apply drops of food colouring


Squirt several drops of blue food colouring onto the shaving cream. The blue food colouring represents your rain. Check the water to see if you can see the food colouring seeping through the shaving cream. If you do not see this, add more food colouring until it goes through.

STEP 4: Enjoy the experiment in action!


Once you see the food colouring rain seeping through the shaving cream, sit back and watch to see what happens. You will want to do this experiment again and again!
