Rainbow after rain...

I am observing many years that Canadian children drawing rainbow, always, everywhere. And suddenly I understood - because they can observe rainbow during the Summer constantly.Why? because everywhere sprinklers sprays water beside each house! And you everywhere can see RAINBOW!
Recently, we were learning about colours, cogwheel and today we were talking how rainbow appears.
We started with our wonderful sunny day and discussed what happen if wind going blow harder and harder?
Of course, it will bring clouds! Clouds may be very-very small and white, but if wind blow harder, They will "run toward each other and cling each other, so they become a huge cloud!"
So, what happen with clouds further? We cut out of the wax paper a few clouds And put they on the window - they were white and almost clear. After that we put clouds one on top each other and figured out that they not transparent any more!!!"I know, said Eric - they going to make a rain!"
We discussed with children what clothes we should wear in rainy day,

Do you know how to open an umbrella?

How raindrops look like?
