Simple question, not sure a simple answer.  I'd like to = make an effect that would appear as if I were pressing my finger through = a wall of water.  Envision a wall of water facing you, hand pushes = straight in, slight angle, index finger extended, and just pushing the = index finger through the wall of water.

It's that entry part that is the real = question.  The wall of water will have enough color to show a = difference with a bright green hue (think The Shape of Water because = that's basically what I'm doing).  As the finger goes through, = naturally, it will then change to the color of the water to indicate it = is within the water.

The entry, a springiness to it, that kind of thing is what = I'm trying to achieve.

Appreciate any thoughts and ideas.
