Have you ever been to a party where they hand out large opague plastic cups? Every party they do is a chance to do cups and balls using napkins as balls and the cups as cups. You can fit raquetballs, toys or many other small items as your final load. It's worth learning to do because you it looks crazy impromptu (and it is). I've had a lot of success with this and have even used water glasses covered with newspaper (this is why I keep my subscription) as a cup.
It's a classic for a reason.
