Geyser Biome

New type of liquid

We should add Geysers to the taiga biome for example we could have a new type of liquid called acid water or something like that. You can pick it up with a bucket and place it, depending on what blocks it gets placed on it has different colors. It can be rainbow sort of like the Grand Prismatic Springs from Yellowstone. Or it can be a green brownish color when you place it on any other blocks, and it will always have campfire smoke coming from the water. When swimming inside the Acid you will take damage. The only way to get acid is by either finding it in the boiling taiga biome or by putting normal water on a new type of block called the boiling magma or just normal magma for a few minutes. The water would become more cloudy and less transparent due to bubbles forming in the water, and this can be scooped up in a bucket. The geysers would have a whole cave underneath the acid with many ores such as gold, diamonds, and emeralds. To find them you need to have trimmed copper armor which will slow down the effects of the acid and it will prevent you from being boiled. We could also use the same mud block from the mangrove in the biome for mud Pots and things like that. 

New biome

It will be a flatland biome surrounded by spruce trees and the main block here will be tuff and limestone. There is a chance to find an erupting geyser that will work similar to old faithful. It will shoot a cloud of smoke and any player standing in the way will be boiled.
