Katrina’s been away on holiday, so we’ve replaced her in this episode with Aaron, an ex Jehovah’s Witness who’s spent some time on the NZ Skeptics committee. Mark and Aaron talk about Aaron’s attempt to prove Mark wrong about Diet Coke, and the lessons learned from this test about blind testing. Bronwyn completes her series on cryonics with a grab-bag of interesting facts she’s learned. And Mark seems to have got more than he bargained for when he looked into a silly idea about how you’re supposed to “implant” seeds so that they can better serve your needs.
