PLEASE DO NOT TRY THIS AT HOME
Six doctors have eaten Lego heads to help advise parents whose young children swallow the plastic toys.
The strange experiment was to show how long it takes them to pass through their digestive systems.
Three women and three men working in paediatrics swallowed Lego heads and then sifted through their bowel movements until they found the toy.
The international team of researchers kept a diary regarding how firm their stools were too, as this could have had an impact on travel time.
By the end of the experiment, the team found their times varied between 1.14 and 3.04 days – with the average being 1.71 days for the toy to pass through their systems.
Unfortunately for one of the participants, the little Lego head was never discovered in his stool. The researchers admit they do not know if he simply missed it or if it has got stuck in his bowels.
