When water is spread on top of lava it creates obsidian but when water and lava collide side to side it creates cobblestone
All you need is obsidion and flint and steel.Form the obsidion five blocks tall and four blocks wide.It should look like a rectangle.After that light the obsidion on fire and the nether portal will apear.If the portal does not show up then you did something wrong.
No, you need a Diamond Pickaxe to collect blocks of Obsidian.
you do not need the edges for a portal so 8 but with edges 12 and it needs to be aranged like this any block to the left and right of the two in the center(perferabaly dirt) you stack two obsidion on top of those then you put a block on top of the two obsidion and put obsidion blocks off of that it should look like this x--x - - - - x--x x stand for no block needed so improvise if you want and - stands for obsidion.
