I used carpentry very deliberately. It's a skill that's seen to require practice, but is still very accessible. Most able-bodied people can build stuff with wood. In fact, most of our grandfathers (assuming American) probably did wood working as a hobby.

It used to be taught to grade school kids. I distinctly remember building adirondack chairs, picnic tables, and benches in wood shop, from dimensional lumber, for use in local parks. Thirteen year old kids can build practical objects using wood, with guidance.

While physics is voodoo. Even genuinely intelligent people have difficulty grasping it.

CS probably lies somewhere in-between, intellectually, but is seen as something that can just be taught to any person and they can be productive.
