Story:
Dr. Anonymous has captured millions of dinosaurs for his experiment. Neutralize liquid chemicals and free the dinos!

Acidic liquids (marked with -) and Alkaline liquids (marked with +) are harmful to the dinos, but once they are combined, they become harmless.
------------------

Rules:
Liquids of the same color and same property (acid, alkali, or neutral) can not be combined, but they can be added on top of each other.
Liquids of the same color but opposite properties can be combined.
Each container (stack) can store at most 4 blocks of liquids. Once it’s full, no more liquid blocks can be added.
Once two liquid blocks of the same color but opposite properties are combined, they become one harmless liquid block.
Goal: neutralize all liquids above all the dinos.
