In 2018, a science experiment went viral because it involved six doctors swallowing LEGO heads just to see how long they would take to pass through their digestive systems. Now the doctors involved have reunited in an article to explain their methods and motivations. Emergency physician Dr. Andrew Tagg was always interested in the many things children swallowed. The most common are coins, followed by plastic toys. There was already research in how long it took to poop out a coin, but none on plastic toys. Meanwhile, frantic parents were searching through toilets to find what had been swallowed. But there was a second motivation, shared by many research doctors- the thrill of an article that might be published in the famous December issue of the British Medical Journal, where odd and often funny studies are highlighted. That desire helped Tagg recruit other pediatric doctors. Then they had to set the parameters, agreeing on coordinating their bowel movements and their methods of searching through them. And they had to choose their toys.
I don’t think anyone specifically went out to buy Lego heads to find which was the tastiest looking one to have. It was much more of a case of which head had the best-looking face to swallow. You want one that looks kind of shocked and scared as it goes down.
Four years on, the doctors give us the lowdown on what they went through to test the passage of the LEGO heads. You won’t regret reading it. -via Metafilter
