Experiments (also known as Experimental Gameplay Template:In) are Minecraft:data packs Template:In or game options Template:In. Experiments allow players to preliminarily test certain unfinished features that may or may not eventually be released in future updates.

Toggling

Experiments are found in the world options when creating or editingTemplate:Only a world. When turning an experiment on an existing world, a copy of the world is created automatically. Template:IN, turning an experiment on disables Minecraft:achievements for the world. Once the world is created with an experiment on, the experiment cannot be turned off again. Worlds with the experiments on have an "Experimental" tag next to the game mode name in the world menu.

Servers

Experiments can be enabled for servers by editing the Template:Cd fileTemplate:Only before generating a world by adding the ID of the experiment to the Template:Cd field in the form of a comma-separated list.

For example, this is how Minecraft:Minecart Improvements can be enabled in Template:Cd:

initial-enabled-packs=vanilla,minecart_improvements

Features may be enabled retroactively to already existing worlds by editing the Template:Cd file in a specialized NBT editor by adding a list tag under "Data" called Template:Code and inserting at least two strings: Template:Code and Template:Code.

Warnings

File:Ore UI - Play Screen or Edit World Screen - Play World Button - Load Experimental World Pop-Ups (Bedrock).png

The warning message that pops up when attempting to play on an experimental world in Bedrock Edition.

The point of experiments is for the player to look at some not-quite-finished or experimental features, which could crash, break, change, or stop working at any point in future updates. When the player attempts to load the experimental world, it shows a warning message before loading it. Attempting to disable the experiments toggle via external tools could also crash and break the world.

It is recommended to create backup copies of the world before enabling any experiments to avoid breaking the world and having issues in future updates.
