This is a test for picket edition creative!
Step 1: The Bricks
You may already know how to make the portal. You can make it with obsidian or the old neather reactor core. For that way you need gold and cobblestone. But can you do it on pocket edition!
Step 2: The Test
I know many ways to make the portal and I tested them on creative.Sadly, none worked. :(
(The image you saw is not a finished portal)
