When I was growing up, we had discovery channel. That sparked my intrinsic curiousity. My daughter has that intrinsic motivation as well, but only for k-pop now. She likes youtube videos and she likes when I tell her about science stuff. Maybe I can combine that by recommending her some good youtube channels.
Also Nile Red and 3brown1blue.
for a more adult audience - Technology Connections. I say adult because I don’t think Alec would hold the attention of a teenager.
NileRed is more adult than T-C based on the type of stuff he messes with being super dangerous sometimes, though. Like, I wouldn’t want a kid messing around with things like manganese heptoxide or various strong acids or whatever that are super dangerous on their own with adults messing with them, let alone kids.
