AirBubble creates a purified microclimate for children to play in, a true bubble of clean air in the centre of Warsaw (Poland). The project is located within the public green space outside of the Copernicus Science Centre (Centrum Nauki Kopernik), a site which will also host a dedicated exhibition illustrating the design innovation behind the invention of AirBubble. The playground integrates the Photo.Synthetica technology for the advanced integration of photosynthesis in the built environment.
