Reaching the Aether

You do not need an achievement or a special item to leave for the Aether - you build a portal, much like a Nether portal, but out of a different material and lit a different way.

• Build the frame out of Glowstone. Stack Glowstone blocks into the same rectangular frame shape you would use for a Nether portal (a hollow standing rectangle).
• Activate it with water. Instead of using flint and steel, use a bucket of water on the inside of the frame. The water triggers the portal and fills it with the glowing gateway.
• Step through to be sent up to the Aether. Stepping back through the same portal returns you to the Overworld.
• The first time you build it, make sure you have gathered enough Glowstone - the frame uses the same number of blocks as a standard portal frame.
