COSMIC SANDBOX GUIDE

OBJECTIVE: A creative physics toy with zero time limits—experiment with fluid dynamics, gravity attractors, and particle synthesis.

Select Matter: Choose Sand (granulates), Water (fluids), Fire (combusts), Gravity (vortex), or Void (black hole).
Paint & Draw: Click and drag or touch anywhere on the canvas to emit streams of matter.
Fluid Interactions: Water flows through sand, fire vaporizes water into steam, and gravity attractors spin matter into galaxies!
