Just fantastic

this is so well done. With Katie’s deep knowledge and Johns wonder of the universe, it’s a pleasure to listen to. You’d think this would be more Hank’s domain but John adds a story telling element to all the mind boggling facts, I’m glad it’s him doing it. Thank you.

John is back!

With Dear Hank & John only once every fortnight, it’s great to get my supplement of John from another source (Hank’s with SciShow Tangents). Plus it’s a great podcast. Go listen!
