So there is no way I could achieve a small enough perturbation through any practical method?

Thanks a lot for the response :) How would I measure a positive Lyapunov constant? And could I do this with an actual football?

Rugby balls and American footballs are prolate spheroids. As such, their bounce patterns seem sporadic - they tend to bounce to different heights and in different directions even when they appear to hit the ground with a constant angle, speed, and spin. Does this behaviour relate to chaos...
