„The Foam Party“ - Ibiza, Spain, 1.9.2008 Ibiza foam parties are the best club craze to burst into the UK and European club scene in recent years. A foam party is a social event in which participants dance to music on a dance floor covered in several feet of suds or bubbles dispensed from a foam machine. For safety reasons, the foam is generated from non-toxic, non-staining, hypo-allergenic solutions.
