Milk

Milk is an item in Minecraft used for curing potion effects and making Cake. Milk is obtained by right-clicking a Cow. Buckets are not stackable, but on the Pocket Edition they are.

Usage
You can milk a cow infinitly, as there is no delay. If making a cake, you get the buckets back. Milk will cure you if you are effected by a potion, so Milk is very useful when fighting wither skeletonsor cave spiders.
