It rains a lot in Seattle in the spring ... and the winter ... and the fall ... and disappointingly, sometimes even in the summer. Needless to say, we have ample opportunities to play in the rain. S and I wanted to give rain painting a go. Unsure of which process would give us the most beautiful rain paintings, we decided to try three different methods and compare them. Since S knows it's best to keep as many things the same as possible in an experiment, she decided to the same three colors (red, yellow, and green) in each method.
First, using a Ziploc baggie and a kitchen mallet, we broke up several colors of inexpensive watercolors (the kind with the little oval cakes of paint). S sprinkled them all over one sheet of watercolor paper.
Next, in a tray, I gave her food coloring to drip on a new sheet of watercolor paper.
And finally, for the third method she added liquid watercolors to another sheet of watercolor paper.
Then, with S in her trusty pink rain boots, we took each painting outside and observed.
After a few minutes, here's what the hammered watercolor cakes looked like:
Here's what the food coloring looked like:
And here's what the liquid watercolors looked like:
Both S and I thought that the most beautiful rain painting was made with food coloring. We were both surprised to see how very different the results of each method were. And now when we want to make a rain painting, we always use food coloring.
