Building the Nether Portal

To build the Nether Portal you will need 14 blocks of obsidian and flint and steel  to build the portal. First put 4 blocks of obsidian on the grass (or any other floor) in a straight line. Then stack four on each edge block (there are two edge blocks). Now the edge blocks should be stacked 5 high. Then connect the sides at the top. Finally use the flint and steel to light the obsidian. When you finish it should look like this!
