My kid went to welding summer camp when he was 8. 12 kids, one instructor; they learnt welding, brazing, soldering, other stuff I don't know the English for. Everyone had a good time and made some amazing things. Nobody suggested there was anything to worry about, but then again those parents wouldn't have signed their kids up. But I never met German parent who were particularly paranoid.

German kids videos and books can be really good too, like the 'was ist was' series that, say, really shows you how internal combustion engines work. I say "can be" because there's a lot of crap there too.

Dallas international school currently has a circus program for elementary and high school students through lone star circus.

I remember welding in shop class in seventh grade in the US. Pretty fun actually. That was more than two decades ago though.

Germany seems to have a lot more "common sense" than the US. Have you seen some of their playgrounds?

Probably just fewer "lawyers" and not more "common sense"

Edit: Added quotes to lawyers because I really meant destroyers of freedom
