As an emergency physician at Western Health, in Melbourne, Australia, Dr. Andy Tagg says he meets a lot of anxious parents whose children have swallowed Lego pieces. Much like Andy so many years ago, the vast majority of kids simply pass the object through their stool within a day or so. But Andy and five other pediatricians wondered, is there a way to give parents extra reassurance ... through science? So the doctors devised an experiment. "Each of them swallowed a Lego head," says science journalist Sabrina Imbler, who wrote about the experiment for The Defector. "They wanted to basically see how long it took to swallow and excrete a plastic toy." On today's episode, Sabrina joins Scientist in Residence Regina G. Barber to chart the journey of six lego heads, and what came out on the other side.
