 Ring chaser. Explain to people what the ring chaser is. As soon as you get on the apparatus, you hit the bar, that ring starts going through. Now you've got to hustle through the bars and then catch that ring before it drops. If you don't catch it before it drops, then you are left with a little small ring that you can pick up and try to get it on top of that peg, which is almost impossible. You've got to have great optical discipline to be able to see it and land it. That's a hard one.
