How to make a Nether Reactor in Minecraft PE

This Minecraft tutorial explains how to make a nether reactor with screenshots and step-by-step instructions.

WARNING: A nether reactor was used in Minecraft PE (before 0.12.1) to bring part of the Nether to the Overworld. Now, you can build a Nether portal to go the Nether!!

This is the nether reactor design that we will build in this tutorial:

You can build a nether reactor, activate it, and then collect some of the unique items from the Nether. But you only have so much time once you activate your nether reactor. When your time runs out, you are left with this netherrack structure.

Required Materials to make a Nether Reactor

In Minecraft PE, these are the materials you can use to craft a nether reactor:

Steps to make a Nether Reactor

1. Add the First Layer

In Minecraft, you need 14 cobblestones, 1 nether reactor core, and 4 blocks of gold to make a nether reactor.

For the first layer, start by placing 4 blocks of gold and 5 cobblestones on the ground. There should be a cobblestone placed between each gold block.

4. Activate the Nether Reactor

Now that your nether reactor has been built, you need to be in Survival mode to activate it. To activate the nether reactor, tap on the nether reactor core in the center of the nether reactor.

You should see a Nether-like world appear around you with the word "Active!" appear in the upper right corner of the screen. Congratulations, you have a limited time to dig up your gold blocks if you want to keep them. Otherwise, they will disappear.
