Kim Goodman (USA) has a unique talent which means she can pop – that’s right, pop! – her eyeballs to a protrusion of 12 mm (0.47 in) beyond her eye sockets 
This record is an iconic Guinness World Records title, which many may remember from the book over the years
Measuring the “pop” is an exact science that has to be done by an optometrist using a device known as a proptometer; an average of three measurements gives the final, eye‑watering result! 
“Proptosis” is the term for eyeball displacement or bulging eyes. Kim discovered her talent when she was hit on the head by a hockey mask, but can now pop out her eyes on cue.
This record-breaking eyeball pop was measured in Istanbul, Turkey, on 2 November 2007
