I mean, not that I would be starting to process film.
Well, hypothetically speaking of course, in case one of your nephews asks you about film development
I use Paterson tanks and reels. They're plastic and the same reel can be adjusted for 35mm or 120. I've owned stainless steel tanks and reels and they're very good, but harder to learn how to load, particularly if you're loading them inside a changing bag.
D-76 is a great general purpose developer but only comes in powder. And once you mix it up, it has a finite shelf life. For that reason I use Kodak HC-110, a thick syrupy concentrate that lasts (seemingly) forever. It's D-76 like in its characteristics.
A 1-litre graduated cyclinder is useful, and a big clean plastic pail or two. If your nephew were to consider HC-110, then a baby syringe (the kind with no needle) is good for measuring out small but accurate quantities of the yellow goo.
Kodak or Ilford Rapid Fixer and a bit of Kodak PhotoFlo are really the only other chemicals you...I mean he...would need... Plus a gallon or 4L jug to store the diluted fixer.
And a couple pairs of film clips, a can opener (church key style). If there's no completely dark room available, a changing bag is perfect (it's what I use).
All in all, probably less than $100US to acquire a starter kit + first-round chemicals.
