Learn how mathematicians use fluid dynamics to determine how many licks it takes to finish a lollipop in this video from *SciTech Now* partner *Science Friday*. The mathematicians make their own lollipops and suspend them in a solution, where they can study how fluid flows around the lollipops, slowly dissolving them. See what ways this method is accurate, and how it differs from an actual lick.

In this video from SciTech Now, learn how mathematicians use fluid dynamics to try and answer how many licks it takes to finish a lollipop.
