I am looking to make a collapsible baton ? Ideas please?

Me and my cousin both really want a collapsible baton and I was hoping to make it  out of copper piping but I am not sure how to make   it  work properly.

For conducting an Orchestra perhaps? If this is intended to be a weapon be aware that is it probably illegal.
+1, There's no reason to have one as a weapon.
