"ET - Cool exhaust effect.

Which filter did you use?"

Filter?...What's a filter? I haven't learned what a filter is yet or how to use it....but I wanna now....Your exhaust kick my cheezy sci-fi special effect's butt!
You are the Pro around here along with the Fuzz.

OK here's how I did the effect. I drew a yellow rectangle, rasterized the layer so I can trim it with the background eraser (by the arms) and I used blending stye: Dissolve and adjusted the intensity with the slider.
