How Do Nuclear Submarines Make Oxygen?

I just love how he isn't afraid to ask every question under the sun and how calm the crew is to answer his questions. It's not like school trips where you can't ask about this or that topic or this machine because you'll be an annoyance.

No, he just straight out points and just asks "what does this do? How does it work? Can I see it work? Oh, so what happens next? Can I see that too?" He's just a child without a filter and the crew seems to enjoy it as well.
