+Whether TNT explodes after activation.=
 An explosive device. When it explodes, it will hurt living beings and destroy blocks around it. TNT has an explosion radius of @1. With a small chance, blocks may drop as an item (as if being mined) rather than being destroyed. TNT can be ignited by tools, explosions, fire, lava and redstone signals.=
