Figure 1.71 days. That was the average time for six courageous volunteers who swallowed a Lego head, then dutifully kept an eye on their bowel movements, reports Forbes. Dead flies, half-sucked candy found on the ground, erasers... and one of the most popular items, besides coins, are small toy parts.
Discovering that your kid has swallowed Lego is pretty annoying as a parent, but these researchers did the same thing in the name of science.
Published in the Journal of Paediatrics and Child Health (yes, seriously), the painstaking dookie review was undertaken by scientists Andrew Tagg, Damian Roland, Grace Leo, Henry Goldstein and Tessa Davis.
Six researchers from Australia and the United Kingdom swallowed yellow Lego heads and kept track of how long it took to poop out the little plastic buggers.
The SHAT results showed that the consistency of the researchers' stools were not affected by the object they swallowed. The amount of time it took to travel from mouth to toilet was also aptly titled - the Found and Retrieved Time (aka the FART) score. "Pre‐ingestion bowel habit was standardised by the Stool Hardness and Transit (SHAT) score", the study read. After what might have been a painful release, the conclusion seems to be that a toy block should pass through in about 1.71 days on average.
"This will reassure parents, and the authors advocate that no parent should be expected to search through their child's feces to prove object retrieval", the researchers said.
Before the volunteers were allowed to swallow the heads of LEGO figures, they're in for three days, keep a diary, where he recorded the time of defecation and the quality of the chair (in accordance with the Bristol scale). The team adds that the claim "could not be statistically validated", but let's all assume the Lego head found its way down the drain at one point or another.
"If it's a small Lego head, you don't need to go poking through their stool", she told the British publication.
