Maroon solid. Destroys particles.

Also, it creates a small amount of pressure.

This element essentially represents the outer boundary of the simulation field. Any particles that travel into it (NOT particles simply touching it) cease being simulated and immediately disappear.

Void is capable of conducting heat, and so clone can be used in combination with Void or Black Hole to make arbitrary temperature regulators.
