Fire Charge

The Fireball is an item that was added in snapshot 12w04a, which can be used in a similar fashion to a Flint and Steel. It is essentially an upgrade to the flint and steel, as the fire spreads faster.

Crafting
Note : In snapshot 12w04a, you can craft this item with 1 coal, 1 gunpowder and 1 blaze powder in any crafting slot.

Dispensing
When a Fire Charge is launched from a dispenser, it acts like a Blaze's fireball and lights the area it touches on fire. Dispensers tend to fire the balls up. They are not affected by gravity, so they will continue on a path out of sight forever, or until coming into contact with something. Both the look and behavior exactly match that of Blaze fireballs, so it is highly likely that these are the same or a sub class of the blaze fireballs.

First look
The item was shown in the 1.1 gui file (item file) in the Minecraft .jar file.

Bugs

 * If you shoot one through a water fall with a dispenser, it will still be on fire.
