Our latest project was to make a cloud rain. I don't know how to make a real cloud rain but mom found a fun experiment on Pinterest to try. All you need is a clear glass or jar filled with water, some shaving cream and food coloring. Make a cloud out of the shaving cream on top of the water and add drops of food coloring until the cloud gets saturated and starts to rain. After the experiment I used different colors to see what would happen the the rain. It was cool, it all turned purple in the end.
