The exhibition of Pedro Wirz Environmental Hangover came to a festive end on May first. In addition to the puzzle booklet and a sound guide, which was created in cooperation with a school group, the seed ball workshop provided a special highlight. Located right in the exhibition and surrounded by the works of Pedro Wirz, 45 participants formed their seed balls out of soil and flower seeds. Safely wrapped and packaged, the seed balls were taken home by the visitors and planted in a free patch of the soil of their choice. This unique sensory experience invited participants to contemplate. It took Environmental Hangover beyond the walls of Kunsthalle Basel and into the gardens of its visitors.
