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 (1) and Minecart (1) 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 off by a player, mob, or Powered Minecart, it will start to go along the rail like a rideable mine cart. It will detonate on these conditions:


 * It moves over powered Activator Rail (after 4 second delay).
 * It derails and falls more than three blocks.
 * It's destroyed while in motion.
 * It's destroyed by fire, lava or an explosion.
 * It hits a full block at the end of the tracks (does not detonate if on powered rails that have power).

Upon detonation, it will act as normal TNT, exploding and damaging nearby scenery, players, and mobs. A useful fact about these TNT mine carts is that upon detonation, it will not destroy it's rails and the blocks the rail is on, with the exception of Powered Rails, so make sure you use normal rails when playing around with TNT mine carts. 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.

Bugs

 * If you detonate a minecart with TNT at the highest building level, it will explode like usual, but then turn pink and start slightly expanding, then contracting, while flashing white
 * In 1.5.1, If you spawn multiple minecarts with TNT on the same block and release them all together, it will glitch out your games sound if u remain near them. it is also possible to retain the sound glitch if u put all the TNT blocks on a small powered circle track. they will not explode when together unless something new gets in its path. also if u pause the game while they are on the track, then it will change sound until u reenter game. It is possible also when doing this to cause visual glitches of floating TNT minecarts. On top of that if u are doing this in creative mode, the explosions (if u are semi near them) will cause a cannon effect, throwing the player hundreds, and even thousands of blocks away (depends on how many carts exploded on each other.

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.
