File:21w03a Water in the Nether no commands.png

Summary
Water can be placed in the nether without commands. Shown in creative but 100% possible in survival. To do so, 1) Place lava next to a full solid block (so soul soil won't work, but netherrack or stone will) 2) Remember the side of the block you placed the lava in 3) Place glow lichen inside the lava, on the side of the block 4) That's it. The lava gets replaced with water to allow the lichen in a waterlogged state
