Another great episode. It's really interesting to see how much of a visual learner Dan is and if he can't visualize something that is when it essentially becomes magic.
Suggestions for future episodes:
Computers - what the different components (CPU, RAM etc) do, maybe tie it back in to how consoles have these components too
Cooking - after watching the video where Dan made a grilled cheese, it seems he views cooking like some kind of alchemical process
Beer - as suggested by someone above, detailing how beer is brewed would be cool
Cars - either how the components in a car (engine, gearbox, transmission, diff) interconnect and work or maybe just something on engines (internal combustion vs electric)
Data - as Dan has mentioned in this episode, he has no idea how the 1s and 0s become something like a picture. Describing data encoding using something like morse code or semaphore might help. Could potentially include spy shit like secret codes and cyphers.
