In Minecraft, portals are used to travel between dimensions. The most common portal is the Nether Portal, which allows you to access the Nether. Here’s how you can make a Nether Portal:

Nether Portal (Overworld to Nether):

Materials Needed:

• Obsidian blocks (minimum 10 blocks)
• Flint and Steel or a Fire Charge

Steps:

1. Mine Obsidian:
   • You need a minimum of 10 obsidian blocks to create a Nether Portal.
   • Mine obsidian using a diamond or netherite pickaxe. To obtain obsidian, you need to pour water over lava source blocks and then mine the resulting obsidian blocks.
2. Create the Portal Frame:
   • Build a rectangular frame using the obsidian blocks. The minimum size for a Nether Portal is 2 blocks wide and 3 blocks high, but it can be larger (e.g., 4 blocks wide and 5 blocks high).
3. Activate the Portal:
   • Use Flint and Steel or a Fire Charge to activate the portal. Right-click (or tap, depending on your platform) on the inside of the portal frame with Flint and Steel or a Fire Charge.
4. Enter the Portal:
   • Once activated, the portal will generate a purple swirling effect. Walk into the portal to be transported to the Nether.

End Portal (Overworld to The End):

Materials Needed:

• Eyes of Ender (minimum 12)
• Stronghold location

Steps:

1. Locate a Stronghold:
   • Use Eyes of Ender to locate a stronghold. Throw the Eyes of Ender, and they will lead you to the nearest stronghold.
2. Find the End Portal Room:
   • Once inside the stronghold, locate the End Portal room. The room contains a frame with portal blocks and empty slots.
3. Activate the Portal:
   • Place Eyes of Ender into the empty slots of the End Portal frame. Each slot requires one Eye of Ender.
4. Complete the Portal:
   • Once all the slots are filled, the portal activates. You’ll see a portal appear in the frame.
5. Enter the Portal:
   • Step into the portal to be transported to The End.

Important Notes:

• Obsidian: Be careful while mining obsidian, as it requires a diamond or netherite pickaxe and takes time to mine.
• Eyes of Ender: Craft Eyes of Ender using blaze powder and ender pearls.
• Stronghold: Strongholds are found randomly generated in the Overworld. They contain the End Portal leading to The End.

Creating a portal is a key aspect of Minecraft gameplay, enabling access to different dimensions and resources.
