In the Nature of Things saw Christchurch teacher Ron Walton deliver science lessons to children. Along with The Night Sky’s Peter Read, Walton made made science pop. The pair were two of NZ’s best known broadcasting personalities of the era, fondly remembered by a generation of Kiwi kids, as well as overseas viewers (Things was a rare NZBC title that sold to the US and other territories). From a (gentler) time well before the pyrotechnics of MythBusters, here Walton — armed with just a pointer, chart and elemental props — puts vitamins under the microscope.
