In this video, a Dad walks his son through building throwing arrows (large lawn darts). It is nice to see examples of good teachable moments. What is also nice about this video is that he shows both advanced and simple ways to do things. Example: Use a band saw to make the slots for the fins, or use a Pull Saw to do it. The only thing that makes me cringe is that neither the dad nor the son ever have a pair of safety glasses on. Safety habits are learned early. Monkey see, monkey do and all that.
