Used tires and plastic bottles for carbonated drinks - it would seem that more garbage things can not be found. But you can consider them as the most fertile material for creativity, literally worthless.
To make such a smiling sun, you will need an old tire and several (in the photo there are 11) plastic bottles. Additionally, you will need some suitable paint and creative inspiration. And a drop of patience, while the sunny face is dry.
Such a sun is absolutely safe, since it does not contain metal parts and is very appropriate on the playground. For the lawn can also serve as a spectacular decoration.
