Water Box: Physics Sandbox

Ragdoll playground meets a floating water sandbox in this physics-based sim. Explore realistic water behavior, experiment with liquids like lava and nitro, and watch up to 200,000 water particles move as you play.

Ship sinking and destruction are central. Build ships from scratch or use 50+ pre-built vessels (cargo ships, submarines, and even the Titanic), test them against waves, bombs, storms, and tsunamis, then watch them float, sink, burn, or explode. Share your experiments in the online workshop and enjoy a deep, chaotic sandbox for endless creations.
