Brain Junk is where Amy Barton and Trace Kerr shake up science, history & culture in the hunt for off the wall, totally unbelievable but true, answers to questions you never knew you wanted to know. What are Supernumerary teeth? Do ants pass the Mirror Test? Why do kids in Denmark get to murder their birthday cakes? We will be cannon balling off the question high dive every Tuesday to bring you the answers -- those of you in the front seats, bring your ponchos -- we're out to flood your brain.
