Water is borderless. Water is trans-scalar. Water is trans-material. Water is transtranscultural. This project explores the multifacetedness of water, its interaction with architecture, and its role as a medium for humanity in the hybrid process of understanding and perceiving the world. Starting with the analysis of the similarities and contrasts between theme waterparks and theme museums, these two are fused into a new building type, creating two intertextual and immersive sequences of scenarios of amplified, sampled, and reinterpreted alternative reality. The architecture here becomes a scope for understanding the relationship between modern urban infrastructures and the bodies living within them. The modern water in new york city, as the theme of both the waterpark and the museum, and as both a physical and a psychological medium, leads the visitors to experience these two interlocked spatial structures of perception and knowledge through its endless, visualized, and touchable flow.
