Are there any vaguely educational things that your 8 year old likes to watch on YouTube?

Just looking for ideas so that I can make suggestions. My 8 year old just wants to watch Ladbaby, and I'd like him to branch out a bit a watch something a bit more beneficial sometimes.

Horrible histories and operation ouch. Both on iPlayer 😀

Thanks, ds is 9, and is now massively into Mark Rober - which made me think back to this thread.
