TNT

TNT acts like a normal block in Creative. However, in Survival it behaves like the Creeper's explosion. Upon being struck by the player, it will start smoking and beeping white. If there are no blocks to hold up the TNT block, activating it will make it affected by gravity and it will fall. After a few seconds, it explodes, destroying a vast amount of blocks, mobs that are nearby, and even the player if they are not careful. Hitting it a second time in survival will stop the countdown and make it so you can pick it up to use later. TNT can clear water and lava. Setting TNT on fire causes it to explode. However, if the TNT falls in water, the explosion will not destroy any blocks at all but still cause damage to the player.
