Everything you never knew you wanted to know. We guarantee, you won't be bored.

Amy Barton and Trace Kerr shake up science, history & culture in this once a week show. We hunt for off the wall, totally unexpected answers to questions and bring them to you in two to five minute short, "Brain Storms" or longer ten to thirty minute episodes.
We dive into questions like: What are Supernumerary teeth? Do ants pass the Mirror Test? Why do kids in Denmark murder their birthday cakes?
Brain Junk is a fun ride for adults and kids who want to know.
