    Because you see the base of the steam from the surface of the water. This creates the effect of the stream bed being elevated to the surface. This happens in water because light travels slower in water than in a vacuum.

    Refraction of light from a dense medium bends the ray away from the normal. As a result objects under water appear closer to the surface than is actually is.
