Next Project...

Well, having taken the crossbow about as far as it can go without building a real one, it's time for a new project.  I have looked around for some other plans and found a book titled "Fun Projects for Dad and the Kids".  In it are some ideas for a spring-powered cannon...  Dunno if I can manage the softball-firing size they mention, but I do have some springs and PVC pipe sufficient to probably fire the larger superballs.  Cannon came in all sorts of sizes, perhaps this will do...
