How Rainbows Form

If you dove into the sun, the first layer you’d hit is hot enough to make diamonds BOIL. Right now we’re in a golden age of new solar science. For the first time, we’re getting close-up pictures of the Sun like we’ve never seen. Sending probes into its atmosphere. And revealing secrets about our star we never thought possible… Trust me, after this video, you’ll never look up at the sun the same way. So let me take you on a journey… INTO THE SUN.

How do you take copper wire, a battery and magnets and make electric train? With science! This super simple DIY physics demo uses electromagnetic induction to propel a train made of magnets and batteries.

Special Relativity and the Twin Paradox

What happens when you drop a perfectly balanced stack of balls? And how is the result like a supernova? The classic momentum transfer demonstration, taken to the next level. A big thank you to my nephews and niece Drew, Max and Whitney for creating the trampoline footage! Thank you to the Vlogbrothers for sponsoring this video, to Kyle Kitzmiller for filming, and to Island School on Kauai for providing the balls (ischool.org).
