I’ve added my favorite YouTube channels in the comments below. (Feel free to check them out!) But, my preferences aside, what YouTube channel(s) do you want more people to see?
Legal Eagle is great at explaining current events and their Legal implications, he also does reviews on movies or shows to explain how they portray law vs reality.
Ordinary Sausage makes sausage out of everything and generally does cooking experiments in a quick and humorous way
Bobby Fingers is a mix of artisan videos where he expertly hand crafts dioramas (mostly) of events while making funny and interesting comments, but he adds some pizazz and production to the whole thing that makes it very engaging.
