Bottle o' Enchanting

The Bottle o' Enchanting (also known as the Experience Potion) is an item which can be used to spawn experience orbs when thrown.

Current (Pre-1.8)
A bottle o' enchanting cannot be brewed, but can be acquired by trading with a villager priest. This is the only way to obtain one legitemately in survival mode. Priests will offer 2–4 bottles o' enchanting for one emerald.

In 1.8
In Minecraft, bottles o' enchanting will be a tier 4 trade of clerics. Each bottle will cost 3–11 emeralds.

Usage
A bottle o' enchanting can be thrown like a Splash Potion. On impact with any object (except for air, lava, and water), it will drop experience orbs worth 3–11 experience points. The bottle o' enchanting breaks on a variety of different surfaces and objects that may not be expected, including mobs and blocks that players can pass through, such as active portals.

Trivia

 * Even though the bottle o' enchanting is green, it gives off blue sparks, and glows purple (as an enchanted item does).
 * Throwing multiple bottles o' enchanting on the ground while flying and then falling will cause the screen to go green/yellow and play the experience sound for sometimes minutes at a time.
 * This can also happen if the player dies with a large amount of experience orbs because the XP flies around the player, making these lights.
 * Repeatedly throwing bottles o' enchanting will create many experience orbs on the ground, which can lead to a noticeable decrease in the FPS rates of players somewhere near the experience orbs. Thus, this can be used as a form of griefing. However, this would mean one must acquire many bottles o' enchanting, which may be difficult in survival mode.
 * When placed in a dispenser, the bottle o' enchanting is treated as a projectile and fired similarly to arrows, snowballs, fire charges, and eggs.
 * This item is the only potion style item in glass bottle shape that can be thrown.
