Ping-pong with a difference

Chris and I have just invented a great new game. In the Louisiana State University Physics and Astronomy Department they have a common room containing a table tennis table. The room is also furnished with ping-pong balls - two orange and two classic ping-pong ball white. This is almost all you need to play table tennis, but unfortunately not quite enough. Yep, we were missing not just one bat, but two, thus making the game impossible, Well that's what you might think, but we are wiley, ingenious physics types. Improvising with our most bat-like appendage, our hands, we were able to play a reasonable game. This did have the problem of slightly hurting our knuckles, when playing a particularly vigorous shot. Casting our eyes around the room we hit upon some other bat-like implements - a fish slice and a tray. These served well and enabled and enjoyable game. We did get some strange looks from people walking passed the room though. Send me your ideas for other racket substitutes.
