How does it work? It's simple!

Oil and water do not mix. That means they're immiscible. When liquids are immiscible, the force of attraction between the molecules of different liquids is less than the force of molecules of the same liquid. In other words, water molecules like sticking to other water molecules more than they do to oil molecules. Here the oil is dyed vibrant colours so the difference is easily seen and fun to watch.
