=== 27. Build a portal to the Nether! ===
You need one more item to enter the Nether: A {{InvSprite|Fire Striker}} fire striker. This item allows you to place fire anywhere in your world. To craft one, you'll need one iron ingot and one piece of {{InvSprite|Flint}} flint. Flint can drop from {{InvSprite|Gravel}} [[gravel]] blocks, which are commonly found underground. Use your shovel to break them faster. Once you've gotten a piece of flint and an iron ingot, place them anywhere in your inventory crafting grid:{{Crafting table|Iron Ingot|foot=y|type=inventory|RESULT=Fire Striker|3=Flint|shapeless=y}}

Now you are ready to build your portal frame. Build a rectangle using the fourteen obsidian you collected earlier like so:

Next, right click the top of one of the two obsidian blocks at the bottom of the portal with your fire striker in your hand. Suddenly, a glowing purple portal will appear inside the portal frame! Don't step into it just yet, as there is still a lot of preparation to do. It is very easy to die in the Nether, so it's best to go prepared.
