The program takes a light-hearted look at the scientific aspects of a modern Christmas. For instance, ingenious new methods of turkey carving will be demonstrated; flashing and bubbling tree lights will be explained; complex Christmas toys will be demonstrated. Our host, Dr. Donald Ivey, welcomes Iris associate from the department of physics at the University of Toronto, Dr. Patterson Hume, to the program. John Livingstone, the director of the Audubon Society of Canada, will also be on the program. In addition, sketches by George Feyer will be seen and a series of puzzles and optical illusions will be presented.
