Discarded bottles found scattered about whilst out walking are resurrected into the sky of Paris. Reparations - A Re-evaluation of Waste - is an interventionist action in which used soft-drink bottles are recycled and transformed into rockets. The ballistic device is made out of a bicycle pump, making it possible to compress a mixture of air and water in the bottles. After a certain amount of vigorous pumping, and the pressure in the bottle reaches its climax, the bottle explodes and its pressurized contents escapes freely. The bottle is thus transformed into a veritable rocket and propelled into the sky.
