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 turns it into a bottle of that splash potion, this also removes $1/3$ of the cauldron's content.

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 maximizes the duration, compared to the feet.

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

A splash water bottle deals 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 adds 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 empties the cauldron and creates an explosion sound (but no actual explosion).

Uncraftable Splash Potion
$$, the uncraftable potion is a splash potion with no effect that is unobtainable in regular gameplay. 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.

Trivia

 * If an enderman is targeted directly by a splash potion, it teleports away before the potion can affect it. However, if an enderman is caught in the splash radius of a potion not aimed at it, it takes damage from the potion.
 * If killed by a splash potion of harming, the death message would be:  was killed by magic
