My model has not been turning out like I expected.  (But that is ok)
From making the model, I though of a few things. 
1.   It is sometimes hard to see where the reflection bounces on the ball.  Sometimes it is on top, bottom or side.
2.  No ball is needed if you just make a round hole at the back of the reflector.  That might be the easiest way because then all you have to do is have a white sheet of paper over the hole and you can always see the laser dots on the paper if it is properly adjusted!

First of all I got a red ball to represent the cooking pot.   This can be suspended a few inches above the table or screwed into the table at that height.
Below the cooking pot, you must have your strips of reflective material laid out. The ideal material might be a thin plastic with reflective material stuck on it.
I might drill holes in the bottom of all the strips and attach them all to a center using a pin or small nail.
I still have not figured out how best to keep the strips in position as I and after I adjust them to the laser points.
I show a procedeure to adjust the strips in the image notes.
If you are willing to have 2 or more bounces of light and (if you want to produce a more exotic  beautiful shape),  Then I suggest you start at strip 10 and work backwards. As your reflections start to go out of range and start missing the target, start using strips 1,2, etc to redirect them!
In this way, you both enlarge the reflector shape and get an exotic and perhaps beautiful shape!
Happy modeling.
