TNT is detonated from being lit on fire (such as from a Flint and Steel ) or from receiving an active redstone current. When using TNT in a redstone circuit it doubles the capacitance over a repeater. There is a 4 seconds fuse time, allowing the player to retreat to a safe distance. After being ignited, it will perform a slight jump in the air before returning to the ground. It will flash white for exactly four seconds and allow the player to move through it, exploding soon afterwards.
The explosion is easily capable of destroying most blocks in the vicinity. Fragile blocks, such as Dirt and Sand , are the most affected, while sturdier types, such as Obsidian , are more resistant to the explosion. TNT does not obey physics until lit, where it will then fall as an entity until it hits a block or detonates. It is a very infamous griefing tool, as a TNT block can easily destroy most blocks besides obsidian and Bedrock . Because of this, it is often banned on servers that don't allow griefing. TNT is a natural block because it naturally appears in Desert Temples and is used as a trap in them.
As of minecraft version 1.7, you can spawn in TNT with a custom fuse time, allowing for TNT that explodes instantly, as well as TNT that takes a long time to explode.
TNT is crafted using Gunpowder and Sand .
