Is that really a bad thing? Minor things like that teach the kids how to handle tools and machinery, so they can operate safely the dangerous tools adults use. Like most boys, I had to learn the hard way to not put my finger in a light socket, and how to not stab myself when the screwdriver slips.
As my professor would say "We learn by doing!" I learned so much from my erector set: about the dangers of spinning objects, how gears mesh, and even seemingly minor things like how frustrating tiny screws and nuts are when you are still learning the required fine motor control.
I took the fine motor control for granted until I saw some young adults unable to get the blade of a screwdriver in the slot, then apply force to keep it in the slot and turn at the same time.
(Maybe that's why people keep reinventing the screw head, so I need multiple sets of screwdrivers. arrgh)
