Minecart with TNT

The Minecart with TNT is a block of TNT inside a minecart.

Obtaining
Minecarts with TNT can be retrieved just like other minecarts, by it.

Usage
Minecart with TNT 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 is destroyed while in motion.
 * It is destroyed by fire, lava or an explosion.
 * It turns on a curved track too fast, with a solid block or entity located beside the track (in the previous movement direction).
 * It is hit by a flaming arrow.

Upon detonation, it will act as normal TNT, exploding and damaging nearby scenery, players, and entities. Upon detonation after activating on activator rail, it will not destroy its rails and the blocks the rail is on, however other nearby carts can. The faster is the minecart, the more powerful the explosion.

Trivia

 * A direct hit from three merged minecarts with TNT can reduce a fully diamond armored player to half a heart.
