Well, adults are supposed to have better judgement than children.
I like my children as I like my phones: batteries fully charged up of play time before it's time to put them to work.
For some people, visiting labs and the like is play time. You haven't met these two kids. He has. Presumably, he knows them better than you do.
I agree with this.
Boeing let me see their 717 and c17 plane factories when I was a kid. Was an insanely fun experience as a kid and formative for who I am now. Glad I did that that particular day rather than hang out with my friends
