I drove my mom crazy with always taking things apart to see how they worked (I ruined a radio, and a toaster doing that), so one of the best gifts I ever got was a see-through robot that you could completely take apart and reassemble (I think it was called Mr Mechanic, or something similar). If I was growing up in today's times, I'd probably be headed for a career in construction (which was NOT a female-friendly field back in the early 60's).
