Dispenser

A Dispenser is a Redstone -related block that dispenses blocks and items that will be added in Update 1.0.0 along with most other Redstone Components. It can be activated by connecting it to a trail of activated redstone, or by placing it directly next to a power source, such as a lever or a button. A Dispenser is very useful in traps, and naturally generates in Jungle Temples as well.

Uses
A Dispenser's main use, like it's name, is to dispense blocks out. There are some exeptions, however. A Dispenser will behave differenly if:
 * Arrows or Fire Charges are placed in it- It will shoot them.
 * Splash Potions are put it- it will splash the potions.
 * Spawn Eggs are put it- It will spawn the mob itself

Trivia

 * A dispenser will not splash the potion if it is not a splash potion.
 * It will be added in 1.0.0
