Physicist Robbert Dijkgraaf sits down with a table full of 7-year-olds to teach them the physics of light and color. It’s an understandably uphill battle, but the kids walk away with a healthy appreciation for the science behind the sky.

In Dr. Dijkgraaf’s defense, it’s not an easy thing to teach to children. When you really think about it, how many natural occurrences can you definitively explain? Not to take the Insane Clown Posse’s side on something, but could you explain how magnets work to children? If you answered yes, we’ve got an 8-minute show we’ll need you to star in.

This is the third episode of the Inverse Original Series Big Ideas with Little Kids, and features some of the headiest science in the show.
