Since 2000 in Brussel three-meter diameter red and green balls are placed in the city to highlight the role of public space. The presence of these huge mobile objects raise the attention to the place and to the people around such as children and youngs who use the urban space. The balls are made by red plastic, inflated by a vacuum cleaner, and in case of
holes easy to be repaired with glue. The balls are used as tools to higlight the lack of place where it is possible to play and share experiences, to raise political awareness about the need for space for young people. They infact can interact with this tool, write on it and move it to other places that also need media and public attention.
