Pick one terrain goal, start with a small Flint and Steel baseline, then compare the same layout with special TNT or Detonator. Scale toward mountain tests only after the crater or drilling result repeats.
The official source confirms terrain goals but not formulas, so this page keeps the method useful without overclaiming.
Crater and mountain experiment checklists with role context and explicit unknown terrain dimensions. The official description supports a progression from tiny craters to flattening entire mountains and names Paint, Cluster, and Drilling TNT as special TNT examples. It does not publish blast radius, terrain health, drilling depth, costs, or exact placement math, so use repeatable observations instead of numbers copied from another Roblox game.
For TNT Voxel Playground crater, the useful question is whether the same setup repeats, not whether an unsupported radius sounds precise.
