The kids I sit for like to watch Symphony of Science videos on YouTube, which is great because they’re basically the coolest thing ever. (Little kids can watch the same thing over and over and over, but these I don’t mind watching on repeat.) This one is my favorite. Stephen Hawking and Carl Sagan, like, what could be better?

I hope y’all know, I have little patience for YouTube videos, and when I post one, it’s really worth watching. I swear. (By the way, this Mister Rogers remix by the same PBS dude behind Symphony of Science is pretty amazing, too.)
