+- Control the position and rotation of any unanchored parts or mechanisms, including replicating `Inf` or `NaN` components in `Datatype.CFrame|CFrames`.
   Set part velocities to extreme values (including `Inf` or `NaN`), which can interfere with the physics of other unanchored parts/assemblies, even those that are not owned by the exploiter.
   This is often used to fling other player characters and nearby parts.
   Manipulate the firing of Touched events, including not firing Touched at all.
