Levitation Potion
Would you like to float above the ground in your favorite game Minecraft? Starting from version Minecraft PE 0.17.0, the ability to levitate has been introduced! Without needing any add-ons, you’ll be able to hover if a Shulker hits you! The Shulker is a new mob in MCPE that spawns in the End dimension!
The Levitation Potion mod for Minecraft Pocket Edition adds an explosive potion that activates the levitation effect for anyone affected by the explosion of the potion bottle. However, this comes at the cost of losing an experience bottle, which will no longer exist in Minecraft Pocket Edition.
The levitation potion replaces the experience bottle. In MCPE, two mobs have been selected as sources for this new potion! To obtain it, you can either find it in creative mode or defeat one of these two mobs:

You can use the explosive levitation potion in both creative and survival modes of Minecraft Pocket Edition. However, I believe it’s most useful in survival mode!
To activate the potion on yourself, simply throw it either above or below you! The effect lasts for 25 seconds, during which time the player or another mob targeted by the potion will float in the air.
For fun, you can throw this potion at any mob in the world of Minecraft Pocket Edition. After 25 seconds, those mobs will fall, and most will die from fall damage.
