Splash Potion

"Wouldn’t it be great if you could trick your opponents into drinking harmful potions to bring about their own demise? Realistically that’s not likely to happen, which is where splash potions come in useful—they can be thrown at mobs or other players so that they’re forced into contact with the effect. Cunning!"

- Stephanie Milton

Splash potions are a variant of potions that can be thrown.

Brewing
Splash potions are brewed by adding gunpowder to a normal potion.

Natural generation
One splash potion of weakness can be found in a brewing stand inside an igloo basement.

Filling bottles
Using a glass bottle on a cauldron that contains splash potion will turn it into a bottle of that splash potion. Using a glass bottle on a cauldron also removes $1/3$ of that cauldron's contents.

Brewing
Lingering potions are brewed by adding dragon's breath to a splash potion.

Using
Splash potions are thrown by them. On impact they explode, applying status effects to nearby entities. The bottle is lost, unlike drinkable potions. Entities within an 8.25×8.25×4.25 cuboid centered on the thrown potion at impact and within 4 blocks euclidean distance of the thrown potion at impact are affected.

The farther away the entity is from the center of the explosion, the lesser the imbued effect. For effects without duration i.e. Healing or Harming, the potency of the effect reduces linearly from 100% on a direct hit to 0% at 4 blocks' distance. For effects with duration, the effect has full potency but the duration decreases linearly on the same scale (rounded to the nearest $1/20$ second), with no effect being applied if the duration would be 1 second or less. Throwing a potion at an entity's head will maximize the duration, compared to the feet.

Splash water bottles
Splash water bottles will have no effect on almost all entities, but will put out fire in the block hit and the four blocks horizontally surrounding it.

A splash water bottle will deal damage to an enderman or a blaze; however, endermen have a chance of teleporting away if hit with one.

Filling cauldrons
Using a splash potion on a cauldron will add one level of that potion to the cauldron. Attempting to add a splash potion to a cauldron with water, dyed water or a non-matching potion will empty the cauldron and create an explosion sound (but no actual explosion).

Uncraftable Splash Potion
The uncraftable potion is a splash potion with no effect that is unobtainable in survival. It is also available in potion and lingering potion forms, as well as for tipped arrows.

It can be obtained using the following command:. It is also obtained any time a potion has invalid or missing potion effect tags, and thus serves as a placeholder.

Custom effects
Splash potions can be obtained with any status effect using and the tag , which is an array of effects for the potion. See Item format for more information, and status effect for a list of effects and IDs.

Item data

 * : The item's tag tag.

Entity data
Splash potions when thrown have entity data which define various properties of the entity.

Trivia

 * If endermen are targeted directly by a splash potion, they will teleport away before the potion can take effect. However, if they are caught in the splash radius of a potion not aimed at them, they will be affected.
 * If killed by a splash potion of harming, the death message would be:  was killed by magic
