Because the eternal Tootsie Pop question plagues even scientists, a team of researchers from NYU and Florida State University set out to discover how many licks it really takes to conquer a lollipop. By studying water currents and candy, they were able to estimate it takes 1,000 licks -- which is significantly fewer than our childhood guess of "5 jillion."
The study, published in the sexy Journal of Fluid Mechanics, involved placing 2in pieces of handmade hard candy in a water tunnel with a controlled current. The scientists then used time-lapse photography to measure how the water flow affected dissolving. Based on the data, they were able to peg the number of licks required to finish a lollipop at 1,000. Though this stat is clearly the most important discovery to come out of the study -- and NYU labs in general -- the researchers also noted their findings could be relevant to geology, what with all those landscapes and erosion.
