Water balloon throwing exhibitions have given rise to some of the most unique and ephemeral outdoor sculptures in the art world. These temporary installations, often created as part of interactive art events, blend playfulness with creativity. One notable example is "Balloon Arch" by artist Joshua Allen Harris, which used hundreds of water balloons to form a shimmering, gravity-defying structure. Another famous piece, "Splash Totem" by collective Pneuhaus, stacked colorful water balloons into a towering, unstable monument that delighted audiences before its inevitable collapse.

The "Liquid Lattice" installation at the 2019 Coachella Valley Music and Arts Festival became an instant sensation, with visitors collaborating to build a sprawling web of water-filled balloons. Similarly, the "Hydro Spheres" project in Tokyo transformed public spaces into interactive playgrounds where participants could contribute to growing, bubble-like sculptures.

What makes these sculptures remarkable is their impermanent nature—existing only for hours or days before melting away. They challenge traditional notions of art by emphasizing process over permanence and audience participation over passive observation. While no physical traces remain, photographs and videos of these breathtaking water balloon sculptures continue to inspire new generations of temporary artists.
