We used a wheel to fire them. It works pretty well. They go about halfway across the width of a gym, and we can make them slower if needed (so as not to harm little kids). A couple of notes: a single wheel creates massive backspin. It was really fun when we had it horizontal, but vertical is better for the bot. Also, the system will vibrate because of the wheel. Our wooden prototype from 2 years ago would vibrate so much that the ping pong balls wouldn't get sucked down into the shooter. The switch to a metal frame fixed it. We still don't have a great indexer working, so no advice there, but we are trying.
