Start to End Action

HI,
I have two questions:
1. Is it required that the golf ball should be visible all the time during different actions?
2. In the event are we allowed to use more than one golf ball?

1. It doesn't specifically specify in the rules, but I believe the golf ball does have to always be visible, or you may have to prove that nothing suspicious is happening behind the scenes. For example, you can have a tunnel for one of your actions, but you would need to show how the tunnel works and that it's only function is a tunnel. That's in a sense why you need to have 2 walls visible, so the judges can see everything that's going on.
2. You definitely need more than one golf ball, in fact your going to need a golf ball for almost every action. Each movable part can only be used for one action, meaning your start ball can't through all of your actions.

You're right - it doesn't say that the golf ball has to be always visible, so it doesn't have to be. The ES may ask you to explain and demonstrate any part of your apparatus that seems unclear if there are questions. But it's fine to use an opaque tube to, for example, transport the start task golf ball to the end spot.
