5 min readThe Bears Who Test Your Garbage Can
Kobak the destroyer was a cub in the Alaskan interior when his mother—a classic "problem bear" accustomed to human food—led her cubs onto a rancher's land and started killing free-range chickens. The rancher shot and killed Kobak's mother and one of her cubs. Kobak and his sister Nikina were rescued, and instead of being euthanized like many problem bears, they hit the lottery: transported to a grizzly bear sanctuary in Montana, where their job is to live happily—and to test supposedly bear-resistant consumer products.
As journalist Alex Davies explains in his book The Destroyer, these bears are the frontline of a strange and little-known world: test engineering. From airplane engines to skyscrapers to pill bottles, the people who figure out whether products are actually safe rely on creative, sometimes bizarre experiments. And as Davies told Ira on Science Friday, the process is always a compromise between what's ideal and what's practical.

Have you ever wondered what it means for something to be bear resistant? How do manufacturers know that the cooler you take camping or the compost bin in your backyard will keep hungry bears out?
Wonder no more! Journalist Alex Davies’ new book “Kobuk the Destroyer: And Other Tales from the Wild, Unseen World of Test Engineering” takes you inside the workplace of the grizzly bears whose job it is to tear apart consumer goods. Davies joins Ira to discuss how bears do it, and other creative experiments to test the safety of jet engines, pill bottles and more.
