Minecart with TNT

The Minecart with TNT is a vehicle added in the 1.5 Redstone Update. It acts as a moving TNT block. It is crafted with TNT and minecart therefore can be created in the simple 2x2 crafting grid in the survival mode inventory. It can only be placed on a rail. Once it is pushed it will start to go along the rail like a rideable minecart. It will detonate on these conditions:


 * It moves over a powered Activator Rail (after 4 second delay like the TNT block).
 * It derails and falls more than three blocks.
 * It's destroyed while in motion.
 * It's destroyed by fire, lava or an explosion.
 * It turns on a curved track with a solid block or entity located beside the track (in the previous movement direction).

Upon detonation, it will act as normal TNT, exploding and damaging nearby scenery, players, and mobs. A useful fact about these TNT minecarts is that upon detonation after activating on Activator Rail, it will not destroy its rails and the blocks the rail is on. Note: Even though the rails and supports will be left unharmed, you will still take damage from the explosion, so make sure to be a reasonable distance from the cart.

Trivia

 * It was, at one point, possible to create an enormous crater using several Minecart with TNT's and having them all detonate at the same time.
 * TNT Minecarts will not destroy rails or their supports upon detonation. It will, however, destroy blocks around and below the supports, so if they are made out of sand, the track will fall apart.
 * They cannot be set off by Flint and Steel or Fire Charges.
 * If you place multiple Minecarts with TNT on a single rail, do this multiple times, and make the TNT Minecarts crash into each other, they will create a huge explosion, sometimes enough to crash the game. This is because all the minecarts are condensed into a single spot.
