Javaify Nether Roof(Stable)

First, build and activate a Nether Portal to enter the Nether. Once you’re inside, make your way up to the Nether ceiling and look for a bedrock block at the highest layer. Place a ladder underneath the bedrock, climb to the top, and position yourself directly below the block. Then, aim an Ender Pearl at the edge of the bedrock while moving forward and throw it. If you get the angle right, the Ender Pearl will glitch you through the bedrock and teleport you onto the Nether Roof. This is similar to the method used in Java Edition.
