Go 'Straya.

University of Melbourne researcher Andrew Tagg and a handful of fearless paediatricians took a couple of Lego heads for the team so they could answer the question "My child swallowed a piece of Lego, how long will it take to exit?"

Based on their Stool Hardness and Transit scores and their Found and Retrieved Time scores, the average journey in this small sample group was 1.7 days.

Apart from one unfortunate paediatrician who still hadn't found his lost yellow head after two weeks of searching.

All up, they concluded swallowed Lego wasn't a huge concern, but according to Tagg:

"Although the majority of items children swallow pass through, some can be dangerous and parents should still be vigilant."
