For her project OUTSIDEIN Tolaas walked with Liverpudlians from the north, west, south and east of the city. Together they paced the city using high-end technology to collect smells from streets and neighbourhoods and recording perceptions and feelings in response to their sense of smell. Informed by these responses, she worked with linguist Andrew Hamer, who specialises in Liverpool's Scouse dialect, to develop a new vocabulary to describe the smells of the city.

Tolaas took the smells she collected on the walks back to her laboratory in Berlin to create unique 'smells' for Liverpool, which are transformed through micro-capsulation, whereby the smells (oils) are encapsulated into micro-eggs, which only open through touch or friction to release the scent. This system can be applied to different surfaces- walls, floors, fabrics and furniture - and in combination with a high-tech diffusion system the smell can be released at intervals in small doses. The scent capsules are situated in four different parts of the building (representing the four different areas of the city and their different smells), so that visitors are able to 'scratch and sniff' Liverpool and carry a limited edition of the smell of Liverpool home with them.
