The Culture Vat is a block that acts as a light source when it is placed down. It is slightly transparent in the middle. It is a dark green on the edges, and a light green on the inside. It has a tint of green where it is see-through. At the top is a gray hole, which is presumably how the DNA is placed inside. At the bottom it is gray and has a large red button.
When DNA or a Plant Fossil is put inside and Bio-Goo is used, eventually a white embryo will form inside the Culture Vat, which will move in place (you may have to right-click the Culture Vat to make it appear). There are currently Three versions of this: the Animal Embryo, the Plant Embryo and The Arthropod Embryo.
To create the culture vat, you will need four blocks of glass, three iron ingots, a slimeball, and a bucket of water, placed in the configuration below.
After a few minutes, if the process does not fail, the DNA will turn into an Animal Egg, Embryo, or Prehistoric Plant which can then be either hatched, put into a mammal, or placed on grass or dirt, respectively.
There is a generally uncommon chance that at any given moment during cultivation of an animal, the cultivator may explode and spawn a Failuresaurus, or rarely a creeper or zombie pigman. However, the explosion doesn't cause any damage to surrounding blocks or players. Instead, the cultivator will be destroyed and leaves a water source block in its place, while spawning various items around it. When a plant embryo fails, instead of one of the previously mentioned mobs, you get a failure plant and the cultivator will be replaced with dirt instead of water.
