How to make a Nether Portal and an End Portal
To make a Nether Portal, you first need to gather at least 10 blocks of obsidian. Obsidian is created when you pour water over a pool of lava, and the most efficient way to harvest it is using a diamond pickaxe. Then you need to make a rectangle. Nether Portals are always 4x5 at the minimum, but can be 23x23 at the maximum. A good way to save time and resources, as well as durability on your pickaxe, is not using the corners. A Nether Portal will work without the corner blocks. Finally, to light your Nether Portal, use a source of fire such as a fire charge or a flint and steel to light your portal. If you have built it correctly, swirling purple portal blocks will appear inside the frame, as well as purple particles being drawn into those portal blocks. A partner Nether Portal will generate in the Nether when you build a Nether Portal in the Overworld, and a partner Nether Portal will generate in the Overworld if you do the reverse.
