How Many Licks Does It Take to Get to the Center of a Lollipop?

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.
