Hey guys I'm back! I'm going to show you how to make the nether portal on minecraft pe! Comment if you want to know how to make my friend in the backround, the wither skeleton! Its simple.

Ok, back to the portal part. Add four blocks of obsidian.

Then put four blocks on top (not 4x4, its 4x5)

Add blocks to make the corners match up.

Add fire in a bottom corner.

Ok thats it! You can decorate the corners or have no corners at all! Hope you enjoyed!
