Reflecting a movie clip?

I was wondering what the best method for reflecting a movie clip would be. I have a bouncing ball that is animated by actionscript, it uses gravity and such to bounce in as a sort of intro to a button bar. Well these balls need to have a reflection and i was wondering what the best way for it would be, such as when the ball bounces in and hits the surface it shows a reflection, then as it bounces the reflection fades then eventually settles. Now i know this can be done with a tween because i have it done with a tween but its not ideal, the reason being because now i found this bounce actionscript code that uses gravity and such to determine how the ball bounces and it would be a bit difficult to time a tween, it can be done yes but i was wondering if anyone had any sort of actionscript solution or other solution for achieve what i am looking to do, thanks in advance.
