Goal feeding ball mechanism?????

If a mechanism were to be designed which spread the pvc goal bars to allow unobstructed feeding of balls into the goal. Would said mechanism be required to be retracted before the end of the match? Or could said mechanism still contact the pvc goal bars once the match time had expired? Any help would be appreciated as we can not post to yahoo via school because of the firewall.

From what I remember from what I have heard (and read), the only rule is that you may not be touching the balls. In fact, the goal can even be on it’s side, and you will get points for the balls that are not touching the ground.

Remember, no intentionally tipping goal.
