3, but A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenga and averaged 252 licks each to the center

In 2015 a scientific study by Mathematicians at New York University, showed approximately 1000 licks. The study was published in the Journal of Fluid Mechanics.

Average of 364 licks is needed to get to the center of a Tootsie Pop, based on experiment performed by a group of engineering students at Purdue University, using licking machine modeled after a human tongue. 20 volunteers also assumed the licking challenge and averaged 252 licks each to the center.
