How many licks does it take to get to the tootsie roll center of a tootsie pop?

"During the 2nd semester of an engineering class at Purdue University,they reported that their 'licking machine,' modeled after a humantongue, took an average of 364 licks to get to the center of aTootsie-Pop. Then they tried to test 20 volunteers and found that ittook the volunteers and average of 252 licks. And then a chemicalengineering doctorate student from the University of Michigan recordedthat his licking machine required an average of 411 licks per TootsiePop. Soon after that, a group of students at Swathmore School usedhuman lickers in a scientific experiment and determined it took anaverage of 144 licks to get to the center of a Tootsie Pop. So thereare the results taken from the only 'official' Tootsie Pop lickingexperiments. The problem we have is the distance of difference thatwas encountered in our studies. But this is the reason for the majordifference in the higher and lower number.......you MUST remember theoverall surface area of everyone's tongue IS NOT the same and thedensity of the papilla(taste buds) IS NOT the same in every person,thus resulting in the difference in the number of licks!"
