The Hat
This isn't really a juggling trick, but it can make a nice start or end to a routine and should impress anyone who hasn't seen it before. Simply lock together the handles of three clubs as shown, and you should be able to place them like a crown on top of your head.
It is possible to flick one club into the air by grabbing the bodies of the other two, however a little practice is usually needed to judge the strength of the throw.
