Lingering Potion

Lingering potions are variants of potions that can be thrown to leave areas with status effects which linger on the ground.

Creating potion clouds
Lingering potions are thrown, like splash potions, by them. On impact they explode, creating a cloud. The cloud is made of the potion particles corresponding to the potion that was thrown.

The cloud starts with a radius of 3 blocks, decreasing to 0 over the course of 30 seconds. During the cloud's existence, any player or mob that walks into it after the first second will get the corresponding status effect; this decreases the radius by a $1/2$ block immediately, causing the cloud to disappear more quickly.

For effects with duration, the duration applied by the cloud is $1/4$ that of the corresponding potion. For effects without duration such as Healing or Harming, the potency of the effect is $1/2$ that of the corresponding potion.

The effect may be applied consecutively if the player or mob remains in the cloud. For example, a player throwing a Lingering Potion of Healing II straight down will consume the cloud within a few seconds while being healed 5 times for a total of health. As far as healing is concerned, this makes the lingering potion much more powerful than the regular or splash potion, provided that the player is away from other mobs or players.

Lingering Potions can also be thrown out of dispensers just like splash potions.

Filling cauldrons
Using a lingering potion on a cauldron will add one level of that potion to the cauldron. Attempting to add a lingering 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 Lingering Potion
The uncraftable potion is a splash potion with no effect that is unobtainable in survival. It is also available in potion and splash 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.

Entity Data
Lingering potions when thrown have entity data which define various properties of the entity. Their entity ID is. What makes it a lingering potion as opposed to a splash potion is that their  tag stores a   item. In Bedrock Edition, this is a distinct entity from the thrown splash potion.
