Sim Pool, VRChat's viral world, has water that washes away your pen strokes

The recently viral VRChat world 'Sim Pool!' has remarkably detailed physics: the pool water even interacts with strokes drawn using the Qv pen tool.

After noticing this, the author ran an experiment — lines drawn near the water get swept and scattered by the currents like floating debris, producing comically chaotic screenshots of orange and blue strokes churning in the water.

It's a fun showcase of how far VR community creators push physics engine mechanics, and explains why the world suddenly became a talking point.
