How do you drink milk in minecraft PE?

To drink milk in minecraft PE, first, you need to have a bucket of milk in your inventory. Tap on the bucket to select it, then tap on the screen where your character is located to drink the milk. This will remove any status effects, such as poison or wither, and consume the bucket in the process, leaving you with an empty bucket. You can refill the empty bucket by right-clicking on a cow.
