the blue liquid is water with a blue dye and the transparent part is oil, like baby oil. Oil and water do not mix and oil is less dense so it floats above.
The figures will be of plastic and less dense than water so they float above. If the density is the same and the oil they can flote anywhere in it, If you make them slightly denser then the oil the will sunk and just touch the water, If you make the feet part denser then the heat they will always flots in the correct orientation.
You can get the same effect in water and air. Because air is less dense than the oil you need an object that has a lower density, So for example use a balloon filled with he
