Our public school teachers have inspired a new group of tinkerers. We had "All Day Science" at school which included a session on taking old electronics apart. The kids were taking things apart all afternoon and evening, siblings and friends included. We dissembled a camera lens and manually figuring out how it worked (close and far) by moving a lever. I really got a kick out of it when they said things like:
"Look, rainbow wires!"
"Hand me the screwdriver"
Wonderful when a little junk science can take experiential learning to new levels.
