Nether Aquai

A water-like substance that's exclusive to the nether. It generates in Nether Wastes, deeper inland. It's poisonous to the Player but perfectly fine to the inhabitants of the Nether. You can bucket it but not for long, as the bucket cannot hold the Acidic Liquid for too long. You can turn them into potions but you have less time to turn the bottle to a potion before it burns away. If it touches Lava, it will turn the Lava to Blackstone. If Lava lands on Nether Aquai, the Aquai will turn into Nether Rack. You can make an infinite Aquai Source.
