This video shows you how to make a Nether Portal in Minecraft. Nether Portals are built with obsidian blocks. You can also make the portal bigger than shown in the video up to 23 x 23 blocks in length and height. You can build or create the Nether Portal by placing the obsidian blocks as described in the Videotutorial and activate it by using a Flint and Steel in the inner side of the Portal Frame. You only need a few seconds to build your own Nether Portal.
