Vsauce is the gold standard for educational YouTube—the kind of channel that makes you feel less guilty about screen time because your kid is learning about quantum mechanics or linguistic relativity instead of watching someone scream at Minecraft.

Michael Stevens has a gift for taking questions nobody thought to ask ('What color is a mirror?' 'How much does the Internet weigh?') and turning them into 20-minute intellectual adventures. The production quality is solid, the science is legit, and the enthusiasm is infectious. Teachers love it, kids request it, and parents can actually sit through it without wanting to claw their eyes out.

That said, this isn't casual viewing. Videos are dense, sometimes abstract, and occasionally venture into territory that's more philosophy-of-consciousness than science-class material. Younger kids or those without a baseline interest in STEM may find it boring or confusing. And it's still YouTube, which means you're one autoplay away from someone's conspiracy theory channel.

But if you've got a curious kid who loves asking 'why?' about everything, Vsauce is one of the best ways they can spend time on the platform.
