I suppose I could explain a little bit in case it isn't obvious in the pic. You shoot the bottom 4 first, and they rotate around and hit the horizontal dowel. Then you shoot the top one, and it levers the dowel out from under the other 4 allowing them to fall back down into position. After I did a dry fit/test run I noticed that if you hit one of the end ones, it would teeter totter the dowel and the other end would flip back around, so I added the little one way things.
