Balloon Skip was the outcome of a three day workshop in Porto, Portugal with twenty participants. Commissioned by S.P.O.T. the main parts to the workshop were a presentation on urban interventions from around the world and who the main protagonists were at the time. The group was then introduced to a pavement location near the centre of Porto and an empty skip. Their brief was to make an intervention using the skip that reacts to location. “Uplifting” become the theme, and the balloons were soon to follow.
