In the popular sandbox video game Minecraft, TNT (Trinitrotoluene) is a powerful explosive block that can be used to destroy terrain and create explosions. To light a TNT block, you will need a flint and steel or a fire charge.
To light a TNT block using a flint and steel, simply hold the flint and steel in your hand and right-click on the TNT block. To light a TNT block using a fire charge, simply throw the fire charge at the TNT block. Once the TNT block is lit, it will explode after a short delay.
