In Minecraft Creative mode, TNT (Trinitrotoluene) can be detonated without the use of a flint and steel or a redstone signal. This can be done by placing a TNT block and then hitting it with any tool or weapon. The explosion will destroy the TNT block and any nearby blocks.
TNT explosions can be used to clear large areas of land, create craters, or simply blow up unwanted structures. They can also be used to create traps or prank other players.
