Haha, i Asked....
Mr.Google and he said
%u2022This is one of the more profound questions ever posed to humankind and animal alike. To test this hypothesis correctly, you must stop counting the moment that the 'center' (the tootsie roll blob at the core of the pop) becomes exposed. That should be considered 'reaching the center' IMO.
%u2022It took me 538 licks.
%u2022It depends on a variety of factors such as the size of your mouth, the amount of saliva, etc. Basically, the world may never know. According to the producers of Tootsie Poops the consensus seems to be between 600-800 licks
%u2022Scientifically: What you have to do is measure the amount of saliva you produce per lick, measure the volume of the Tootsie Pop, find the amount each lick your saliva takes away from the pop, and divide that much by the total volume of the Tootsie Pop.
Anecdotally: "I just did it today and it takes 446 licks to get to the chewy center of a loli pop. both of my friends did it today too and we are all 13 years old. One of them got 442 and the other got 449. So, around 450 licks to get to the center of
a Tootsie Pop
I spent three hours counting with my friend we got 765, 902, 730, and 877. So on average about 800
So its a confusing question, based on many factors. Happy Xmas :)
