The HaHaHouse in Zagreb is the first museum dedicated to laughter, opened on the International Day of Laughter. It combines humour, art, and technology, featuring playful installations and interactive displays. Visitors must pass through a happiness scanner before entering. The museum aims to enhance mental health by providing laughter and relaxation, especially during stressful times like the COVID-19 lockdown. Comic book characters serve as guides, and visitors can explore different types of humour. Teljes cikk (Euronews.com)
