Well...at least mine can!
Since I don't think his little hands are quite ready to feed film onto a plastic reel in the confines of a black bag, I did that part for him. But come to think of it, I'll sacrifice some expired film this weekend just so he can practice.
For this first venture into the world of processing, my kid poured the chemicals in and out of the tank, and kept hawk-like eyes on the stopwatch. We used Diafine since temperature and precision timing aren't critical to this cheap two-part developer, plus we can skip the Stop bath step. He was so elated to see the film be pulled off the reels. "Just like Christmas" I told him.
For next time I'll probably get some rubber gloves since the use of Fixer made me a little nervous. Academic principals reinforced: Focus, counting backwards, following directions, manipulatives. All great practice particularly if your child is ADD/ADHD.
