Minecraft (Pocket Edition)
Usage / Purpose
TNT is, as you might expect, a powerful explosive. It can only be ignited with a Flint and Steel. While TNT clears out large areas of blocks it decimates them in the process, making it an ineffective tool for mining.
TNT is stored in stacks of up to 64 units.
One of the central ingredients for TNT is Gunpowder which is only obtainable as a drop from Creepers.
